Used Car Prices Are Shifting: Where’s the Best Value in October 2026?

If you’re shopping for a used car this autumn, the headlines can feel confusing. Electric cars are attracting more interest, while prices for some petrol and diesel vehicles are easing. So where should you put your money?

At DriveRight UK, our advice is simple: start with your needs, then assess the value of the individual vehicle. A market trend is useful context, but it cannot tell you whether a particular car is right for you.

What’s happening to used car prices?

According to Auto Trader’s report published on 9 October 2026, demand for used electric cars rose 40% year on year in September. Their like-for-like asking prices increased 2.8%, while petrol prices fell 1% and diesel prices fell 0.8%.

Across the used market overall, like-for-like asking prices were down 1% on September last year. These are advertised prices, rather than confirmed sale prices, and individual models can behave very differently.

Could petrol or diesel offer better value?

Softer prices may create opportunities, especially if you’re flexible about make, specification and age. However, a cheaper purchase can still prove expensive if it brings large repair bills or high running costs.

Think about your regular journeys. Compare suitable petrol and diesel options using realistic annual mileage, fuel costs, insurance quotes and servicing requirements. For a diesel, investigate whether the model suits your driving pattern and check any emissions restrictions relevant to your routes.

Is a used electric car still worth considering?

Yes, provided it fits your lifestyle and budget. Before choosing one, work out where you would charge, what that charging would cost and whether its real-world range covers your journeys comfortably.

Check the battery’s condition, remaining manufacturer warranty and service history. Ask for available battery health evidence, confirm charging compatibility and consider winter journeys as well as summer driving. Compare the complete ownership cost with a suitable petrol or hybrid alternative.

Look beyond the advertised discount

Two cars with similar prices can offer very different value. Mileage, maintenance records, previous damage, tyres, specification and warranty cover all deserve attention.

Build a shortlist and compare like for like. Check the MOT history, investigate outstanding finance and write-off records, and arrange an appropriate inspection. If buying on finance, compare the total amount payable as well as the monthly payment. Leave room in your budget for maintenance and unexpected costs.

Buy with confidence this autumn

The best-value car is one that meets your needs, has a credible history and makes sense financially. There is no need to rush simply because a headline suggests prices are moving.
