At first glance
• Figures Auto Express published on 29 October suggest some electric cars lose more than 70% of their value over three years and 36,000 miles.
• Our top 10 starts with a Fiat 500e expected to be worth about £8,475 in part-exchange (a 2023 car is about £13,000 at a dealer) and ends with a Porsche Taycan more than £111,000 below its new price.
• Electric cars registered before April 2025 never pay the £440 Expensive Car Supplement, so even a used Taycan costs £200 a year to tax, but get a battery health report before you buy.

The figures are what each car is expected to fetch in part-exchange after three years and 36,000 miles, measured against today's list price, so they show what a dealer would pay you (a forecourt will ask more) and they're a guide to the size of the drop rather than an exact price for a 2023 car. Plenty of EVs were sold with big discounts when new, too, so not every first owner lost quite this much. To show you what you'd actually pay, we've also looked at what dealers are asking for 2023 cars right now, and given our best estimate for each, rounded and based on typical mileage, so expect a bit either side depending on spec and condition.
1. Fiat 500e
Average price new: £28,035 | Expected part-ex value after three years: about £8,475 | Below new price: £19,560
Typical 2023 car at a dealer now: about £13,000
The 500e has the lowest part-ex value in our top 10 and it's also one of the most fun, because the 500e is as stylish and easy to park as the petrol 500 that inspired it. It's best suited to town driving and shorter trips, and at this price it makes a brilliant second car.
2. Citroen e-C4
Average price new: £32,895 | Expected part-ex value after three years: about £9,125 | Below new price: £23,770
Typical 2023 car at a dealer now: about £12,500
Citroen has always put comfort first, and the e-C4 is no exception, with a soft ride that suits long motorway runs as well as the school run. For around the price of a used supermini, you get a proper family hatchback.
3. Vauxhall Corsa Electric
Average price new: £32,635 | Expected part-ex value after three years: about £9,275 | Below new price: £23,360
Typical 2023 car at a dealer now: about £12,000
The Corsa is one of the most familiar cars on British roads, so the electric version is an easy step if you're new to EVs. It's small enough for town and roomy enough for a young family, and Vauxhall's battery warranty passes to the next owner.
4. Vauxhall Astra Electric
Average price new: £37,250 | Expected part-ex value after three years: about £10,425 | Below new price: £26,825
Typical 2023 car at a dealer now: about £15,000
Step up from the Corsa and the Astra Electric gives you more space for barely more money, which makes it one of the best-value family EVs here. Like the other Vauxhalls, its battery is covered for eight years or 100,000 miles (with a promise of at least 70% of its original capacity), so a three-year-old car still has around five years of cover left.
5. Vauxhall Mokka Electric
Average price new: £38,105 | Expected part-ex value after three years: about £12,175 | Below new price: £25,930
Typical 2023 car at a dealer now: about £13,500
If you like the higher driving position of a small SUV, the Mokka Electric (called the Mokka-e until 2023) brings bold looks and a raised seat for around £13,500 at a dealer. It's a good fit for drivers who mostly stick to town and shorter commutes.
6. Lexus UX 300e
Average price new: £51,145 | Expected part-ex value after three years: about £13,950 | Below new price: £37,195
Typical 2023 car at a dealer now: about £16,000
This is our pick of the top 10. In percentage terms the UX 300e loses more value than any other car on the list (it's expected to keep just 27% of its price), yet it comes from a brand with an excellent reputation for reliability, and Lexus UK will stretch its eight-year, 100,000-mile battery warranty to 10 years or 600,000 miles as long as the car has had the battery health check that comes with each service, so ask to see the service history.
7. Subaru Solterra
Average price new: £52,495 | Expected part-ex value after three years: about £15,575 | Below new price: £36,920
Typical 2023 car at a dealer now: about £20,000
Subaru is known for four-wheel drive, and the Solterra brings that to an electric SUV, so it's one to consider if you live somewhere rural or deal with plenty of bad weather. It's expected to be worth less than a third of its price new.
8. Genesis GV60
Average price new: £58,515 | Expected part-ex value after three years: about £20,750 | Below new price: £37,765
Typical 2023 car at a dealer now: about £21,500
Genesis is Hyundai's luxury brand, and the GV60 gives you a properly upmarket cabin and distinctive styling for around £21,500 at a dealer. It's still a rare sight in the UK, which is part of its appeal.
9. Ford Mustang Mach-E
Average price new: £74,550 | Expected part-ex value after three years: about £23,775 | Below new price: £50,775
Typical 2023 car at a dealer now: from about £22,000
The Mach-E puts a famous name on a roomy electric SUV, and at more than £50,000 below its new price it's a lot of car for the money. It's a strong choice if you need family space and want something that feels special.
10. Porsche Taycan
Average price new: £162,255 | Expected part-ex value after three years: about £50,475 | Below new price: £111,780
Typical 2023 car at a dealer now: about £60,000, from around £51,000
If you've always fancied a Porsche, this is the eye-opener of the list, with a Taycan expected to be worth more than £111,000 less than new after three years, and 2023 cars are already at dealers from around £51,000. Tax is the pleasant surprise, because a Taycan registered before April 2025 pays the same £200 a year as a Fiat 500e, but tyres, insurance and servicing are still Porsche prices, so get quotes before you take the plunge.
What to check before buying a used electric car
Ask for a battery health report, which shows how much of the battery's original capacity is left, and check how long the battery warranty has to run. Make sure the charging cables come with the car and look through its MOT history, and if you've never run an EV before, (LINK: Regit piece on home vs public charging costs) shows how much cheaper it is to charge at home.
Electric cars have paid road tax since April 2025, and the standard rate is now £200 a year. The good news for used buyers is that the £440 Expensive Car Supplement doesn't apply to any zero-emission car registered before 1 April 2025, however much it cost new, so any car on this list bought at three years old pays just £200. Newer EVs with a list price over £50,000 pay the supplement from their second year to their sixth, which is worth knowing if you're eyeing a nearly new Taycan or Mach-E.
From April 2028 electric cars will also pay 3p a mile on top of road tax, which works out at about £210 a year if you cover 7,000 miles, and our (LINK: Regit Budget 2026 page) has the latest on it.
When you've found one you like, put its registration into Regit's free car tax checker and you'll see straight away whether it pays £200 a year or £640 with the supplement.
Our verdict
This is a very good time to be buying a used electric car. The Fiat 500e, Citroen e-C4 and Corsa Electric are the most affordable ways into a nearly new EV, the Lexus UX 300e is our pick of the top 10, and if you've always fancied a Porsche, a Taycan that costs £200 a year to tax is hard to ignore. Get a battery health report, check the warranty, and you could drive away with a real bargain.
