Used car prices in 2026: the surge premium buyers need to read

News · 19 Jun 2026 · Michael Harrison

Used car prices are rising at their fastest rate in three years, and premium buyers are the ones who need to read the small print. Auto Trader’s Retail Price Index, the industry’s most-watched used-market gauge, recorded its strongest price growth in three years this spring. In April the average used car reached £17,397 after a 1.8% monthly jump, the sharpest since November 2021, and the momentum carried through May. Demand is holding up, supply is tightening, and used electric cars are leading the field. For anyone weighing a premium used buy or a part-exchange right now, the question is no longer whether to wait for prices to fall. It is where the value still hides.

What the latest used car prices data actually shows

The headline from Auto Trader’s Retail Price Index is straightforward: used values are firming, not falling. The average used car hit £17,397 in April 2026 on a 1.8% monthly increase, and the index went on to record its strongest price growth in three years through the spring, with cars selling faster as demand stayed resilient. That matters because the received wisdom since 2023 was that used prices were drifting back to earth after the pandemic spike. The data says the opposite is happening in 2026, and it is being driven by a shortage of supply rather than a frenzy of speculation.

The supply squeeze is the part worth understanding. Far fewer new cars were built and registered in 2020 and 2021, so the steady stream of five-to-seven-year-old cars that normally feeds the used market is thinning out, and Auto Trader expects that band of stock to keep shrinking over the next two years. Fewer good used cars chasing steady demand is a recipe for firmer prices, and that is exactly what the index is now reporting.

Why used electric cars are leading the climb

The standout in Auto Trader’s data is electric. Demand for used EVs rose 59% year-on-year in April, comfortably outpacing the wider market, and the reason is no mystery. Premium electric cars took brutal first-owner depreciation over the last two years, and that pain has become the second buyer’s gain. A nearly-new electric SUV or saloon that shed tens of thousands in its first three years now looks like genuine value to a used buyer who never had to absorb that loss. Buyers have noticed, and they are voting with their deposits.

That is the tension at the heart of the market: the cars climbing fastest in demand are also the ones that fell hardest. The used Audi e-tron GT is a clean example, with the e-tron GT shedding up to £50,000 in three years showing exactly how steep that first-owner drop can be. The used Porsche Taycan at around £40,000 tells a similar story. The depreciation that punished the first owner is the discount the second one pockets.

The premium EVs climbing fastest in demand are the same ones that fell hardest on depreciation. The first owner took the loss; the used buyer is collecting the discount.

If you are buying premium, here is where the value still sits

Firming prices do not mean there are no deals; they mean the deals have moved. On the combustion side, clean low-mileage premium cars are holding their money, so a sharp buy now is about condition and history rather than waiting for a price crash that the data says is not coming. The bargains, such as they are, sit in premium used electric. Before you assume that makes every used EV a winner, weigh the risks honestly: battery health, warranty cover and residual uncertainty all matter, which is why the three-year residual risk on a used Tesla Model S and X and the two-year reality of Mercedes EQE SUV depreciation are worth reading before you commit.

One trap to sidestep: if you are financing the purchase on PCP, a firmer used market does not rescue you from a poorly structured deal. The optional final payment is still set against a future value, and the warning about balloon payments and EV depreciation applies whether prices are rising or falling. Buy the car, not the monthly.

If you are selling or part-exchanging, this is your window

The flip side of firm prices is good news if you are the one selling. A market with tight supply and resilient demand is exactly when a clean, well-documented car commands its money, so if you have been sitting on a premium part-exchange waiting for the right moment, the numbers say the moment is now rather than later. Get a current valuation from Auto Trader or a comparable tool before you walk into a dealer, take the part-exchange figure in writing, and remember that a strong price on your old car can quietly be eaten by a soft discount on the new one. The two numbers are negotiated together, and a sharp seller keeps them separate.

Where the smart money goes from here

If I were spending in this market, the call would be simple. The single best value on a premium budget right now is a nearly-new used electric car that has already taken its depreciation hit, bought with battery health checked and warranty confirmed, and the depreciation-led bargains spreading across the used EV market are where the genuine savings live. If you are holding a clean premium combustion car, there is no urgency to sell into a rising market unless you actually need to, and if you are part-exchanging, do it now while values are firm and negotiate the two halves of the deal as separate fights. The one thing the data takes off the table is the strategy of waiting for used prices to tumble. In mid-2026, they are doing the opposite, and the buyers who understand that are the ones shopping in the right aisle.
