A 2021 Hagerty comparison offers historical evidence about differences among models and marques, while a separate 2026 study covers five-year-old vehicles broadly rather than ranking supercars.
What the available data can—and cannot—tell you
Depreciation comparisons are meaningful only when their basis is clear. A percentage measured from a new car’s MSRP is not necessarily the same as one measured from an above-list purchase price, and a value change since launch is not directly comparable with a resale estimate at a fixed vehicle age.
Hagerty’s May 2021 comparison examined models from Aston Martin, Audi, Bentley, Ferrari, Lamborghini, McLaren, Mercedes-Benz, and Porsche, generally priced from $100,000 (£70,000) to below $500,000 (£350,000), excluding optional extras. Hagerty says it combined more than 24,000 policy quote data points with information from AutoTrader UK, Premier Financial, and Woodside Credit, grouping cars by marque, model, sub-model, model year, body style, and engine type.
Hagerty reported typical depreciation of about 6% after one year and 20% after three years for cars in its studied set. These are historical figures for that sample—not current estimates for every supercar. The accessible report summary does not provide a complete ranked table, so it cannot substantiate a definitive top ten.

Historical model examples from Hagerty
| Model or group | Reported finding | How to interpret it |
|---|---|---|
| Ferrari 488 Pista Coupe | About 6% above value one year after launch, then about 7% below by year three | A launch-period example from Hagerty’s 2021 comparison; launch demand can affect the starting point. |
| Porsche 911 GT2 RS | About 30% decline since launch | A specific historical comparison, not a current prediction for every GT2 RS or 911. |
| Aston Martin and McLaren models in Hagerty’s sample | Roughly one-fifth to one-quarter depreciation over three years | A finding about the models and period studied, not a permanent rule about either marque. |
| Ferrari and Lamborghini models in Hagerty’s sample | Tended to depreciate less than the German marques studied | A relative result within that sample, not a guarantee of future value retention. |
| Lamborghini Huracán and Audi R8 5.2 V10 | Hagerty said the Huracán depreciated more modestly | A study-specific comparison; individual variants and market conditions can differ. |
Hagerty also reported that convertibles in its accessible set generally depreciated less than coupe counterparts, with exceptions for the Mercedes-Benz AMG GT and Porsche 911 Turbo. It associated greater depreciation among Porsche 911 GT3 variants than Turbo coupes with speculation. These observations describe the study, not universal outcomes.
Why depreciation differs between supercars
Launch demand and the price paid
A car launched amid exceptional demand may briefly sell above list. If a later resale is compared with that inflated purchase price, the apparent loss can be especially large. MSRP, the first buyer’s actual transaction price, and later estimated or completed-sale values are different reference points.

Model, variant, and body style
Different versions of one model can follow different value paths. Hagerty’s analysis grouped vehicles by details including sub-model, model year, body style, and engine type, and its findings included exceptions to broad coupe-versus-convertible patterns. A model name alone is not enough to establish a precise depreciation rate.
Market and measurement period
Geography and timing matter. Hagerty’s historical comparison used UK and US data, while the 2026 iSeeCars study reported by The Car Guide examined US transactions for five-year-old vehicles from March 2025 through February 2026. Results from these different samples and methods should not be combined into a single ranking.

Ownership costs and condition
Maintenance, insurance, service history, and the condition of an individual car can affect what a buyer will pay. Market averages cannot establish whether a specific used supercar is sound or predict its future repair costs. Buyers should check the exact model and year’s value history and arrange an independent pre-purchase inspection.
Useful context: cars that held value in a broader study
The Car Guide’s report on the 2026 iSeeCars study says it covered more than 950,000 five-year-old vehicle transactions in the United States during March 2025 through February 2026. It reported average five-year depreciation of 41.8% across vehicles. The Porsche 718 Cayman (9.6%), Porsche 911 (11.1%), and Chevrolet Corvette (18.7%) appeared as strong-retention examples—not as fast depreciators or as a supercar ranking.

The Car Guide quoted iSeeCars Executive Analyst Karl Brauer: “It’s interesting to note that the two Porsches, plus one Lexus coupe, are the only luxury models to make the top 25 ranking for retained value.” That observation concerns the study’s retained-value list, not the fastest-depreciating supercars.
Independent reader supportYour contribution helps us test, update, and keep practical guides available for everyone.How to compare depreciation responsibly
- Choose one market and a defined time window, such as a specified number of years after purchase.
- Compare the same model year, sub-model, engine, and body style where possible.
- State whether the starting point is MSRP or the actual original transaction price.
- Identify whether the figures are asking prices, estimated values, or completed-sale prices.
- Check the history and condition of the individual car; a model-level average is not a valuation or inspection.
FAQ
Which ten supercars depreciate the fastest?
The available research does not support a current, comparable top-ten list. Hagerty’s accessible 2021 summary provides selected historical examples but not the complete ranked table, and the available 2026 iSeeCars coverage is about vehicles broadly rather than a supercar top ten.

How much do supercars typically depreciate?
Hagerty reported about 6% after one year and 20% after three years for the cars in its 2021 studied set. Those historical sample averages should not be treated as current rates for every supercar.
Does early depreciation mean a supercar will never become collectible?
No. Early value loss alone does not establish whether a car will become collectible later. Hagerty cautions against treating early depreciation as proof of future collectability or non-collectability.
Why can two versions of the same supercar lose value differently?
Model year, sub-model, engine, body style, market, launch conditions, and the original purchase price can all affect comparisons. Hagerty’s study found differences across these categories and reported exceptions to general patterns.
