Car Depreciation: Why Predicted Resale Values Don't Tell the Whole Story

Six months ago, nobody knew quite what the British summer would bring. Forecasts and long-range predictions could point us in a direction, but they couldn't tell us what would actually happen. Fast-forward to August and England and Wales have experienced their driest July on record, with drought affecting much of the country. Predicting the future, it turns out, is difficult.

Car depreciation is no different. Every day, buyers are presented with remarkably precise predictions of what a new car should be worth in three years' time, typically based on the industry-standard 36,000-mile benchmark. Yet today's used-car market is awash with examples that tell a very different story. Some cars have retained thousands of pounds more than expected; others have plummeted despite predictions of strong residual values. Add enormous new-car discounts and pre-registered deals into the equation, and the amount buyers actually lose can bear surprisingly little resemblance to the headline figures.

To find out just how different prediction and reality can be, we've assembled a 20-car cross-section of the market where values haven't performed quite as anticipated. From affordable superminis to luxury SUVs and sports cars, the results demonstrate why predicted residual values should never be taken as a guarantee — and why buyers should always research the real market before committing their money.

Suzuki Ignis (2023)

RRP From: £17,349
Pre-Reg From: c.£16,500
3yr / 36k Predicted Value: c.51% / c.£8,850
3yr / 36k Actual Retail Value: c.£12,000 / c.69%
Value Retained vs Pre-Reg Price: c.73%

The Ignis demonstrates how affordable, distinctive cars can outperform conventional depreciation forecasts. A predicted three-year value of around £8,850 suggested buyers could expect to lose almost half of the original £17,349 list price. In reality, comparable 2023 cars are still retailing for around £12,000, retaining roughly 69% of their original value. Even against a more realistic pre-registered purchase price of around £16,500, that represents 73% retained. Limited supply, low running costs and the Ignis's unusual position as a tiny, lightweight crossover appear to have helped values remain remarkably resilient.

Fiat Panda (2023)

RRP From: £14,740
Pre-Reg From: c.£13,000
3yr / 36k Predicted Value: c.48% / c.£7,100
3yr / 36k Actual Retail Value: c.£9,000 / c.61%
Value Retained vs Pre-Reg Price: c.69%

The Panda tells a remarkably similar story to the Ignis. Its predicted three-year value of around £7,100 suggested a fairly typical depreciation curve, yet comparable 2023 cars are still retailing for around £9,000, retaining roughly 61% of their original list price and 69% of a typical pre-registered price. Much of that resilience comes from the Panda occupying an increasingly scarce position in the market: a genuinely small, affordable mild-hybrid city car with relatively few direct alternatives. With new city cars disappearing and demand remaining healthy, used buyers have fewer places to turn.

Toyota Yaris (2023)

RRP From: £22,125
Pre-Reg From: c.£20,500
3yr / 36k Predicted Value: c.57% / c.£12,600
3yr / 36k Actual Retail Value: c.£14,000 / c.63%
Value Retained vs Pre-Reg Price: c.68%

The Yaris was always expected to perform relatively well, but even its strong predicted residual value appears to have underestimated demand. Comparable 2023 cars are still retailing for around £14,000, retaining roughly 63% of their original list price and 68% of a typical pre-registered price. Toyota's reputation for reliability and the Yaris's efficient hybrid powertrain, low running costs and popularity with owners all help explain its resilience. Buyers should be careful when comparing cheaper advertisements, however, as the UK used market contains numerous imported Japanese-market Yaris models that can distort headline asking prices.

Vauxhall Corsa (2023)

RRP From: £18,585
Pre-Reg From: c.£15,000
3yr / 36k Predicted Value: c.41% / c.£7,600
3yr / 36k Actual Retail Value: c.£9,000 / c.48%
Value Retained vs Pre-Reg Price: c.60%

The Corsa also performed better than predicted, with comparable 2023 cars retaining around 48% of their original list price rather than the forecast 41%. However, the more interesting figure is what happens when substantial new-car discounts are taken into account. Pre-registered examples could be bought for around £15,000 rather than the £18,585 list price, meaning a car now retailing for approximately £9,000 has retained around 60% of that more realistic purchase price. It demonstrates why depreciation measured purely against RRP can exaggerate the amount of money an individual buyer actually loses.

Volkswagen ID.3 (2023)

RRP From: £37,115
Pre-Reg From: c.£32,000
3yr / 36k Predicted Value: c.52% / c.£19,300
3yr / 36k Actual Retail Value: c.£14,500 / c.39%
Value Retained vs Pre-Reg Price: c.45%

The ID.3 shows the opposite side of the story. Its predicted three-year value of around £19,300 suggested it would retain 52% of its original list price, yet comparable 2023 cars are now retailing for closer to £14,500, or just 39%. Even allowing for pre-registered discounts, that represents only around 45% retained. Electric cars have proved particularly difficult to forecast as prices, technology and demand have changed rapidly, while German models have not always delivered the residual-value strength traditionally expected of them. The ID.3 demonstrates how an apparently reassuring forecast can quickly become outdated.

Mazda 3 (2023)

RRP From: £23,945
Pre-Reg From: c.£22,000
3yr / 36k Predicted Value: c.48% / c.£11,500
3yr / 36k Actual Retail Value: c.£14,500 / c.61%
Value Retained vs Pre-Reg Price: c.66%

The Mazda 3 is another car that appears to have been underestimated. Its relatively modest £23,945 starting price gave it a useful head start, yet comparable 2023 cars are still retailing for around £14,500, retaining roughly 61% of their original value rather than the predicted 48%. Even against a typical pre-registered price of around £22,000, approximately 66% remains. A comfortable, well-built interior, strong standard equipment and an increasingly unusual position as a conventional family hatchback have helped make the Mazda 3 considerably more resilient than the original forecasts suggested.

SEAT Arona (2023)

RRP From: £21,695
Pre-Reg From: c.£18,500
3yr / 36k Predicted Value: c.45% / c.£9,760
3yr / 36k Actual Retail Value: c.£11,000 / c.51%
Value Retained vs Pre-Reg Price: c.59%

The Arona has also performed better than its original forecast suggested. A predicted three-year value of around £9,760 represented just 45% of its original list price, yet comparable 2023 cars are still retailing for approximately £11,000, or 51%. More importantly, pre-registered examples could be bought for around £18,500, increasing the proportion retained to roughly 59%. Sharing much of its underlying technology with Volkswagen Group models gives the Arona proven German engineering without the typically higher German-brand RRP, while its practical interior and compact dimensions have helped maintain healthy used demand.

Nissan Juke (2023)

RRP From: £20,985
Pre-Reg From: c.£17,000
3yr / 36k Predicted Value: c.45% / c.£9,440
3yr / 36k Actual Retail Value: c.£11,000 / c.52%
Value Retained vs Pre-Reg Price: c.65%

The Juke is another example where substantial pre-registered discounts worked against the original depreciation forecast. Its predicted three-year value of around £9,440 represented just 45% of the £20,985 list price, yet comparable 2023 cars are still retailing for approximately £11,000. More importantly, pre-registered examples could be bought for around £17,000, meaning roughly 65% of that more realistic purchase price remains today. Strong demand for small SUVs has undoubtedly helped, but the Juke demonstrates how buying at a substantial discount when new can completely change the depreciation calculation.

Dacia Jogger (2023)

RRP From: £17,165
Pre-Reg From: c.£16,000
3yr / 36k Predicted Value: c.55% / c.£9,440
3yr / 36k Actual Retail Value: c.£12,500 / c.73%
Value Retained vs Pre-Reg Price: c.78%

The Jogger is one of the clearest examples of the original predictions underestimating the market. Despite already starting at an unusually low £17,165, it was predicted to retain around £9,440 after three years. Comparable 2023 cars are instead retailing for approximately £12,500 — an impressive 73% of the original RRP and 78% of a typical pre-registered purchase price. Its combination of seven seats, enormous practicality and genuinely affordable pricing remains difficult to replicate, leaving used buyers with relatively few alternatives. Dacia didn't simply make the Jogger cheap; it gave it a niche that has proved remarkably resistant to depreciation.

MG HS (2023)

RRP From: £23,495
Pre-Reg From: c.£18,500
3yr / 36k Predicted Value: c.46% / c.£10,810
3yr / 36k Actual Retail Value: c.£12,000 / c.51%
Value Retained vs Pre-Reg Price: c.65%

The HS is another case where the original RRP tells only part of the story. Its predicted three-year value of around £10,810 represented 46% of list price, while comparable 2023 cars are actually retailing for around £12,000. More importantly, pre-registered examples could be bought for approximately £18,500. That means a buyer paying the discounted price has lost around £6,500 over three years — equivalent to just £181 per month in depreciation. For a spacious, well-equipped family SUV, that makes the HS's real-world ownership cost considerably more impressive than its predicted residual value suggested.

Hyundai Santa Fe (2023)

RRP From: £42,890
Pre-Reg From: c.£38,000
3yr / 36k Predicted Value: c.54% / c.£23,160
3yr / 36k Actual Retail Value: c.£27,000 / c.63%
Value Retained vs Pre-Reg Price: c.71%

The Santa Fe is a particularly strong result for Hyundai. Its predicted three-year value of around £23,160 represented 54% of the original list price, yet comparable 2023 cars are still retailing for approximately £27,000, retaining a much healthier 63%. Against a typical pre-registered price of around £38,000, that rises to an impressive 71%. The Santa Fe's combination of genuine seven-seat practicality, generous equipment, strong hybrid options and increasingly premium feel has clearly translated into used-market desirability, demonstrating how far Hyundai has progressed from its old reputation as primarily a value-focused brand.

Range Rover Velar (2023)

RRP From: £55,330
Pre-Reg From: c.£51,500
3yr / 36k Predicted Value: c.62% / c.£34,300
3yr / 36k Actual Retail Value: c.£28,000 / c.51%
Value Retained vs Pre-Reg Price: c.54%

The Velar shows that a premium badge doesn't automatically guarantee strong residual values. It was predicted to retain around 62% of its original £55,330 list price after three years, yet comparable 2023 cars are now retailing for closer to £28,000, or 51%. Even against a typical pre-registered price, only around 54% remains. This isn't necessarily a wider Land Rover problem — the larger Range Rover Sport has generally proved more resilient. Instead, the Velar demonstrates how individual models can perform very differently, and why paying for a premium badge doesn't always guarantee a better return when it comes to resale.

Alfa Romeo Giulia (2023)

RRP From: £43,259
Pre-Reg From: c.£36,500
3yr / 36k Predicted Value: c.41% / c.£17,700
3yr / 36k Actual Retail Value: c.£28,000 / c.65%
Value Retained vs Pre-Reg Price: c.77%

The Giulia is one of the biggest surprises in our comparison. A predicted three-year value of around £17,700 suggested it would retain just 41% of its original list price, yet comparable 2023 cars are still retailing for around £28,000 — roughly 65%. Against a typical pre-registered purchase price of £36,500, an impressive 77% remains. It also challenges the assumption that an SUV is automatically the safer place to put your money. Despite being a traditional sports saloon in an increasingly SUV-dominated market, the Giulia has comfortably outperformed the experts' expectations.

Citroën C5 X (2023)

RRP From: £28,670
Pre-Reg From: c.£23,000
3yr / 36k Predicted Value: c.44% / c.£12,615
3yr / 36k Actual Retail Value: c.£13,500 / c.47%
Value Retained vs Pre-Reg Price: c.59%

The C5 X is a particularly interesting example because its headline depreciation has landed fairly close to the original forecast. A three-year value of around £12,615 was predicted, while comparable 2023 cars are now retailing for roughly £13,500. But that misses the effect of the substantial discounts available when new. Pre-registered cars could be bought for around £23,000 rather than the £28,670 RRP, meaning approximately 59% of that more realistic purchase price remains today. For such a large, comfortable and distinctive family car, buying at the right price has made the C5 X a surprisingly strong value proposition over three years.

Lexus ES (2023)

RRP From: £40,000
Pre-Reg From: c.£36,000
3yr / 36k Predicted Value: c.44% / c.£17,600
3yr / 36k Actual Retail Value: c.£27,500 / c.69%
Value Retained vs Pre-Reg Price: c.76%

The ES provides further evidence of just how valuable Toyota Group's reputation for hybrid efficiency and reliability can be in the used market. A predicted three-year value of around £17,600 suggested it would retain only 44% of its original £40,000 list price, yet comparable 2023 cars are still retailing for approximately £27,500 — an impressive 69%. Against a typical pre-registered price of around £36,000, that rises to 76%. Its proven hybrid technology, excellent refinement and strong reputation for dependability have helped the ES comfortably outperform the original predictions.

Volvo V90 (2023)

RRP From: £50,315
Pre-Reg From: c.£45,000
3yr / 36k Predicted Value: c.49% / c.£24,655
3yr / 36k Actual Retail Value: c.£30,000 / c.60%
Value Retained vs Pre-Reg Price: c.67%

The V90 is another traditional body style that has performed considerably better than expected. Its predicted three-year value of around £24,655 represented 49% of the original £50,315 list price, yet comparable 2023 cars are still retailing for approximately £30,000, or 60%. Against a typical pre-registered price of around £45,000, roughly 67% remains. Large estates may have fallen out of fashion as SUVs have taken over the market, but the V90's combination of space, comfort, distinctive Scandinavian design and increasingly limited competition appears to have helped support demand for good used examples.

Mercedes-Benz EQS (2023)

RRP From: £102,160
Pre-Reg From: c.£102,000
3yr / 36k Predicted Value: c.53% / c.£54,140
3yr / 36k Actual Retail Value: c.£43,000 / c.42%
Value Retained vs Pre-Reg Price: c.42%

The EQS is where the numbers become difficult to ignore. Industry experts predicted a three-year value of around £54,140, yet comparable 2023 cars are now retailing for closer to £43,000 — just 42% of the original £102,160 list price. Unlike several cars in our comparison, there was also little pre-registered discount to cushion that fall, meaning an early buyer could realistically have lost around £59,000 in three years — roughly £1,640 every month in depreciation alone. Rapidly developing EV technology, a six-figure starting price and a difficult used market for luxury electric cars have made the EQS one of our most dramatic examples.

Porsche Taycan 4S (2023)

RRP From: £90,755
Pre-Reg From: c.£90,000
3yr / 36k Predicted Value: c.75% / c.£68,070
3yr / 36k Actual Retail Value: c.£42,000 / c.46%
Value Retained vs Pre-Reg Price: c.47%

The Taycan 4S is perhaps the most striking example in our entire comparison. Industry forecasts suggested it could retain around 75% of its £90,755 list price after three years, putting its predicted value at approximately £68,070. In reality, comparable cars are now retailing for around £42,000 — just 46% of the original RRP. It highlights several recurring weaknesses in depreciation forecasting at once: premium German cars, large luxury saloons and rapidly evolving EVs can all be overestimated. The Taycan remains hugely desirable, but desirability and an expensive badge haven't translated into the residual values experts expected.

BMW M3 (2023)

RRP From: £81,195
Pre-Reg From: c.£69,995
3yr / 36k Predicted Value: c.50% / c.£40,600
3yr / 36k Actual Retail Value: c.£56,000 / c.69%
Value Retained vs Pre-Reg Price: c.80%

The M3 proves that German performance cars don't automatically follow the same depreciation story. Industry forecasts suggested a three-year value of around £40,600, yet comparable 2023 cars are still retailing for approximately £56,000 — an impressive 69% of RRP and 80% of a typical pre-registered price. Part of that resilience may come from an increasingly unusual position in the market. As traditional rivals have become heavier, electrified or plug-in hybrid performance cars, the six-cylinder M3 has retained a more focused character, helping push it into a distinctive segment of its own.

Toyota GR Yaris (2023)

RRP From: £32,205
Pre-Reg From: c.£32,205
3yr / 36k Predicted Value: c.60% / c.£19,300
3yr / 36k Actual Retail Value: c.£29,000 / c.90%
Value Retained vs Pre-Reg Price: c.90%

The GR Yaris is the standout winner in our comparison, and another major result for Toyota Group. Industry forecasts suggested it would retain around 60% of its £32,205 list price after three years — already a strong prediction — yet comparable 2023 cars are still retailing for approximately £29,000, representing an extraordinary 90%. With virtually no meaningful pre-registered discount to change the calculation, that resilience is genuine. Limited supply, enormous enthusiast demand and its rally-inspired engineering have made the GR Yaris far more than another hot hatch, with used values comfortably outperforming even the experts' optimistic expectations.

What Does This Tell Us About Depreciation?

The biggest lesson is that depreciation forecasts are useful guides, not guarantees. Across our 20 cars, some predictions proved remarkably pessimistic, while others underestimated losses by tens of thousands of pounds.

More importantly, RRP doesn't always represent what buyers actually paid. Pre-registered discounts can completely transform the ownership calculation, while scarcity, reliability, changing technology and simple used-car demand can push values in directions the experts never anticipated. The GR Yaris retaining around 90% while the Taycan 4S retains 46% demonstrates just how unpredictable the market can be.

The answer isn't to ignore depreciation forecasts — it's to never rely on them alone.
