Best Used Electric Cars

The electric revolution is well and truly here, and the used EV market in 2025 is buzzing with options that won't shock your bank balance! Gone are the days when buying a second-hand electric car meant compromising on range or gambling on questionable battery health. 

Today's used EV market is packed with capable performers that have proven their staying power. Here are our top three standout electric options in 2025:

Kia Niro EV (2019-2024)

Typical used price range: £14,500 to £22,000 depending on age, specification and mileage

The Kia Niro EV has proven itself to be one of the most reliable electric vehicles on the road, with owners reporting very few issues even after several years of use. With its practical crossover design, 282-mile range (on the 64kWh model), and comprehensive manufacturer warranty that transfers to subsequent owners, it proves to be excellent value for money.

Why we recommend it:

The Kia Niro EV combines practical and usable space for the family with genuine long-range capability and rock-solid reliability. We think models from 2020 and 2021 are the best option in terms of on-board technology included as standard.

Watch out for:

Check for battery degradation on high-mileage second-hand models, and check that software updates have been applied prior to purchase.

Volkswagen ID.3 (2020-2024)

Typical used price range: £16,000 to £25,000 depending on battery size and specification

The Volkswagen ID.3 has matured into a solid used car purchase, with any software issues found in earlier models now resolved through regular updates. The 100% electric version retains its practical hatchback design for a spacious interior and range options from 205 to 340 miles, depending on battery size.

Why we recommend it:

As you’d expect from Volkswagen, the ID.3 model boasts excellent build quality with a premium interior feel and good charging capability, and it is now available at increasingly accessible prices since newer models have been introduced.

Watch out for:

Avoid earlier models with outdated software and always check the battery's state of health via the car's diagnostics before you agree to purchase.

MG4 EV (2022-2024)

Typical used price range: £13,500 to £20,000 depending on battery size and trim level

The MG4 EV is incredible value in the used market, offering driving performance and range that matches vehicles costing thousands of pounds more. With up to 281 miles of range on top-spec models and a surprisingly engaging experience for drivers, we think it's a standout, budget-friendly option that should be considered.

Why we recommend it:

Brimming with technology, the MG4 EV is already proving popular for its practical hatchback design and head-turning looks and just happens to be one of the most affordable routes into EV ownership.

Watch out for:

Build quality issues on very early examples and ensure that any recall work has been completed before you choose to invest.

Best Used Hybrid Cars

If you’re not quite ready to go fully electric, then you're in good company. Hybrid cars continue to offer the perfect middle ground in 2025, combining the best of both worlds with impressive fuel economy and the peace of mind of a traditional engine when you need it. 

These fuel-sipping champions have matured beautifully, with technology that's been refined over countless miles of real-world driving. Here are our top three used hybrid recommendations: 

Toyota Corolla Hybrid (2019-2024)

Typical used price range: £13,000 to £22,000 depending on age of the car, body style and mileage

Toyota's reputation for hybrid reliability is unmatched, and the Corolla continues this tradition. Available in hatchback, saloon, and estate body styles, the hybrid variant combines excellent fuel economy (up to 62mpg) with low maintenance costs and proven durability.

Why we recommend it:

Exceptional reliability records across the Toyota range, low running costs, and strong residual values make the Corolla Hybrid model a pretty safe investment with minimal depreciation to worry about.

Watch out for:

Ensure regular hybrid system checks have been carried out on the vehicle prior to purchase, and check for any accident damage that might affect battery placement.

Honda Jazz Hybrid (2020-2024)

Typical used price range: £12,000 to £19,000 depending on specification and mileage

The Honda Jazz has a surprising amount of interior space within a compact exterior, with its innovative "Magic Seats" design providing that sought-after versatility. The efficient hybrid system delivers a consistent 60+ mpg in real-world driving conditions.

Why we recommend it:

Thanks to its reliability record, clever interior design, and low running costs, we think the Honda Jazz makes an ideal choice for city-based drivers on a budget.

Watch out for: 

The Honda Jazz Hybrid on the used car market can be hard to come by as owners tend to hang on to them for a long time. When one does become available for sale, be prepared to move quickly! 

Hyundai Tucson Hybrid (2021-2024)

Typical used price range: £18,000to £28,000 depending on specification and mileage

For those needing more space, the Hyundai Tucson Hybrid provides SUV practicality with impressive efficiency. Its bold styling has aged well, and the hybrid system balances performance with economy very effectively.

Why we recommend it:

What we love about the Hyundai Tucson is its spacious interior, comprehensive standard equipment, and remaining manufacturer warranty, which make this a safe family used car purchase.

Watch out for:

It’s important to check that all software updates have been applied prior to purchase, and we’d suggest checking for any evidence of off-road use that might have damaged undercarriage hybrid components.

Best Used Petrol Cars

While electric cars might be grabbing a lot of the headlines, don’t write off good old petrol motors just yet! Traditional petrol engines have been quietly evolving into refined, efficient powerhouses that still make perfect sense for many drivers in 2025. 

With impressive reliability, affordable maintenance, and no charging cables in sight, petrol-powered cars are still a good investment. Our top three used petrol car recommendations are:

Mazda3 (2019-2024)

Typical used price range: £11,000 to £19,000 depending on engine variant, specification and age of vehicle

The popularity of the Mazda 3 can be attributed to its near-premium quality at mainstream prices. As such, anyone in the market for a used model can expect exceptional build quality and refined naturally-aspirated engines that have proven reliability records.

Why we recommend it:

The Mazda3 has a distinct upmarket feel about it. Drivers seem to particularly like the engaged handling, and alongside its proven mechanical simplicity, this makes the car a smart long-term ownership prospect.

Watch out for:

Before purchasing a used model, ensure the service history is complete, as the engines rely on regular maintenance for true longevity.

Skoda Octavia (2020-2024)

Typical used price range: £13,500 to £22,000 depending on engine size, body style and specification

The Skoda Octavia is best known for its generous amount of interior space for ultimate family practicality - particularly in estate form. Benefiting from Volkswagen Group underpinnings and engines, the Octavia cleverly combines German engineering with top-value pricing.

Why we recommend it:

As you’d imagine, the Skoda Octavia has a huge amount of boot space without losing its refined road manners. We think the excellent build quality makes this car ideal for families or those who need maximum versatility from their vehicle.

Watch out for:

There have been previous concerns about the direct-shift gearbox having issues in high-mileage models, so ensure you see an up-to-date service book before making any commitments.

Ford Puma (2020-2024)

Typical used price range: £12,000 to £20,000 depending on engine and specification

The Puma has proven to be one of Ford's most successful models in recent years, largely due to its SUV styling that many drivers now demand. The innovative "MegaBox" underfloor storage in the boot adds genuine extra space for uber practicality.

Why we recommend it:

The Ford Puma is renowned for an engaging driving experience, which is made all the more efficient thanks to the mild-hybrid engines on many models.

Watch out for:

Infotainment system glitches were reported on some Puma models. Any cars that were recalled have now been fixed, but it’s worth checking the system first-hand before purchase. 

Best Used Diesel Cars

Despite all the doom and gloom you may read online, diesel engines still have a place for those who regularly drive long journeys or tow heavy loads. 

Even in 2025, modern diesel power provides a blend of marathon-distance economy and muscular torque that many drivers still desire. Here are our top three best used diesel car recommendations: 

Volkswagen Golf TDI (2020-2023)

Typical used price range: £14,000 to £23,000 depending on engine output and specification

The Volkswagen Golf still maintains its position as the benchmark of the family hatchback segment. The TDI (turbocharged direct injection) engines strike a balance between all-round performance and remarkable fuel economy..

Why we recommend it:

We particularly love the Volkswagen Golf’s premium cabin quality, refined driving manners, and potential for 65+ mpg on longer journeys - great for high-mileage users.

Watch out for:

AdBlue system issues and ensure the particulate filter has been properly regenerated through regular motorway driving.

Mercedes-Benz C-Class (2018-2022)

Typical used price range: £16,000 to £26,000 depending on specification and mileage

The previous generation Mercedes-Benz C-Class can be picked up on the used car market at an excellent price, given the impressive build quality typical with German marques. The diesel engines offer a good balance of performance and economy, with most holding up well even during business ownership.

Why we recommend it:

It goes without saying that the C-Class has premium badge appeal. That, alongside exceptional motorway performance and robust engineering, makes this a smart executive car choice.

Watch out for:

Ensure all servicing has been carried out at the correct intervals by qualified technicians, and check for any outstanding software updates before you commit to buying a used model.

Peugeot 3008 BlueHDi (2018-2022)

Typical used price range: £14,000 to £22,000 depending on specification and mileage

The Peugeot 3008 has aged extremely well, with its distinctive styling still looking fresh in 2025. The BlueHDi engines are renowned for impressive fuel economy without sacrificing performance, and the interior design remains distinctive and upmarket.

Why we recommend it:

A good-looking car inside and out, the Peugeot 3008 SUV is a practical family car fitted with efficient engines that make this a characterful alternative to more mainstream choices.

Watch out for:

Reports of flaws with some of the electronic i-Cockpit infotainment systems. Always ensure you fully test the car before buying. 

Best Budget Used Cars Under £10,000

If you’re on a particularly tight budget, then you’ll be keen to find out what trustworthy used cars you can buy for under £10,000. The good news is that even in 2025, getting your hands on a reliable motor that doesn’t leave you in debt is still possible. Here are three budget used cars to get excited about:

Suzuki Swift (2017-2021)

Typical used price range: £5,500 to £9,500 depending on age and specification

The compact-sized Suzuki Swift may just surprise you. It offers a good performance on the road, reasonable equipment levels, and fantastic reliability for a bargain price. To keep running costs low, its lightweight construction makes it more economical at the fuel pumps.

Why we recommend it:

The lovable Suzuki Swift is not only fun to drive but very easy to park, too! If you’re on a budget, then the cheaper insurance group makes this car ideal for new drivers or as a low-cost second car.

Watch out for:

The downside is that the basic interior materials can show wear and tear more easily, so check the interior carefully.

Toyota Yaris (2017-2020)

Typical used price range: £6,000-£10,000 depending on age and specification

The previous generation Toyota Yaris has been praised for its reliability score, with many models still running perfectly well. Due to its small size and economical engines, running costs for the Yaris are extremely low, and it's relatively easy to get hold of second-hand parts. 

Why we recommend it:

We love the Toyota Yaris for its bulletproof reliability, low insurance rates, and excellent fuel economy that make this little motor the perfect practical runabout.

Watch out for:

Being a budget-friendly car, you can expect to find limited equipment on base models, so we suggest you opt for mid-spec versions for the best balance of value and features.

Dacia Sandero Stepway (2019-2022)

Typical used price range: £6,500-£10,000 depending on age and specification

The second-generation Dacia Sandero Stepway is probably one of the cheapest family-sized SUVs available. Drivers love the car for its raised ride height and robust styling. Its simple mechanical design and shared components with Renault models ensure affordable maintenance for long-term ownership.

Why we recommend it:

Aside from the practical SUV elements, the Dacia Sandero Stepway has a decent amount of equipment for the price and is nice to drive, making it a no-nonsense budget option.

Watch out for:

Earlier models have much more basic safety equipment, and it’s worth checking for any evidence of heavy use.

When to Buy a Used Car in 2025

Choosing the right time to buy a used car can significantly impact the price you pay. Here are the best times during the year to make a purchase:

January

Post-Christmas financial pressure and the arrival of new registration plates in March typically make January a buyer's market with dealers eager to clear used stock.

Early Summer

The used market often softens in June and July as people focus on holidays rather than car purchases.

Late September

As the next new reg plate vehicles arrive, there's often an influx of part-exchanged vehicles hitting the market, creating more choice and negotiation opportunities.

Financing Your Used Car Purchase in 2025

If you think finance deals are just for shiny new models, then think again! Used car finance has evolved with options to rival anything available for brand-new vehicles. Gone are the days when buying used meant emptying your savings account or settling for basic bank loans with eye-watering interest rates.

Today's used car buyers can access bespoke finance packages that work with your budget, not against it. From flexible PCP deals that keep monthly payments surprisingly affordable to straightforward HP agreements that build equity with every payment, the used car finance landscape is more accessible and customer-friendly than ever before.

Below, we break down your options and help you find the perfect payment plan for your next used car purchase:

Personal Contract Purchase (PCP)

Personal Contract Purchase is a popular choice for newer used cars (typically 1 to 4 years old), offering lower monthly payments but requiring a final balloon payment to own the vehicle outright. Find out more about how PCP works here. 

Hire Purchase (HP)

Hire Purchase provides straightforward financing for used cars with higher monthly payments but full ownership at the end of the term without additional payments. Understand how HP works here. 

Frequently Asked Questions About Used Cars

Q: What’s considered good battery health for a used EV?

A: For used EVs, it’s vital you check the battery health. Look for cars with battery health certificates, or budget for a professional pre-purchase inspection that includes detailed battery diagnostics. Most newer EVs retain at least 90% of their battery capacity after five years of typical road use.

Q: What year used cars are compliant with ULEZ?

A: With more cities implementing or expanding clean air zones, ensure any used car purchase meets the required emissions standards to avoid daily charges. Generally, petrol cars registered after 2005 and diesel cars after September 2015 (Euro 6) comply with most low-emission zones, including ULEZ in London.

Q: Are diesel cars still worth buying in 2025?

A: For high-mileage drivers covering more than 12,000 miles a year, Euro 6 diesel engines still make financial sense. However, consider future clean air zone restrictions in areas where you regularly travel.

Q: What is the best age to buy a used electric car?

A: Three-year-old electric cars typically offer the best balance between modern technology, remaining warranty, and depreciation. Battery technology from 2021 onwards is generally reliable, with minimal degradation.

Q: How important is a used car warranty?

A: With vehicles getting increasingly complex, used car warranties provide valuable peace of mind, particularly for vehicles with advanced technology or electric powertrains. For cars over five years old, third-party warranties covering major mechanical components offer a good compromise.

Q: Should I still consider a used petrol car in 2025?

A: Absolutely, you should. For drivers covering fewer than 10,000 miles annually, modern petrol engines offer reliability, reasonable economy, and lower purchase costs than equivalent hybrid or electric alternatives.

Q: How much should I budget for repairs when buying a used car?

A: A good rule of thumb is to set aside 15% to 20% of the car's purchase price for potential maintenance over the first two years of ownership. This percentage should increase for luxury or performance vehicles.
