Buying a used car shouldn’t feel like a gamble. That’s why we’ve compiled this list of the most reliable secondhand motors you can buy in the UK right now. It’s based on a unique mix of real-world data – including warranty claims, MoT results, owner reviews and fleet reliability stats – giving you the best chance of choosing a dependable car that won’t leave you stranded or cost a fortune to fix.
Unlike lists that only rely on surveys or brand reputation, our rankings also reflect how quickly cars get fixed when something does go wrong. That’s because reliability isn’t just about how rarely a car breaks; it’s also about how easy and affordable it is to put right.
We’ve compared info from aftermarket warranty provider, Warrantywise, which releases real-world claims data – including average cost – with the results from the latest Fleet News FN50 awards that reveal the Top 10 most reliable new and nearly-new cars over the lifespan of a typical lease.
The resulting line-up is heavily skewed towards Japanese and Korean cars, but there’s good news if you like BMWs or fancy a Tesla. The aftermarket warranty claims data suggests Toyota, Hyundai and Kia won’t be regretting their long manufacturer guarantees.

Parkers best used car 2025
Spares and servicing costs will be higher than for many rivals, so it’s important to budget for slightly pricier maintenance.

Check the suspension for knocks or clunks, as worn bushes and dampers can crop up on higher-mileage examples. Also, make sure all the interior electronics are working properly, as fixing tech features like iDrive can get expensive. Despite these considerations, the F30 remains one of the best all-rounders on the used market, offering driving fun, comfort and a dash of premium appeal.

FAQs: Most reliable used cars buying guide
-
How does Parkers measure reliability?
We don’t just rely on one piece of information to decide which cars are the most reliable. Instead, we look at lots of different sources, including warranty claim data, MoT pass rates, feedback from Parkers Owners’ Reviews, and fleet reliability figures like the FN50 survey. We also consider how quickly dealers can fix cars when they do go wrong. Altogether, this helps us paint a proper picture of how cars perform in real life.
This way, we can spot cars that might not have flashy reputations but turn out to be dependable workhorses. It also helps us avoid recommending cars that look great on paper but might cost you a fortune if they keep breaking down. Our aim is to help you find a car that’s as hassle-free as possible. -
Which cars are the most reliable to buy used?
Some of the most reliable used cars you can buy right now include the Toyota Auris, Honda Jazz, and Skoda Octavia. These cars regularly appear near the top of reliability surveys and owner feedback, thanks to solid engineering and fewer reported problems. They’re popular choices for drivers who want a car they can trust, without the constant worry of big repair bills.
Of course, reliability can still vary depending on things like which engine you choose and how well a car has been looked after. So even if you’re shopping for one of these reliable models, it’s still worth checking the service history and looking out for common issues specific to that car. Starting with one of these proven choices just makes it far less likely you’ll end up with a troublesome motor. -
Why does dealer downtime matter?
Even cars that are known for being reliable can develop faults every now and then. The important thing is how quickly those faults get sorted out, so you’re not stuck without your car for ages. Dealer downtime tells us how long franchised garages take to diagnose problems and carry out repairs, which can make a big difference to your experience as an owner.
If you rely on your car for work, family life or just getting around, a long wait for repairs can be a real headache. A car that’s reliable and also backed by a good dealer network means less time off the road and more peace of mind. That’s why dealer downtime is part of how we judge the best used cars for reliability. -
Are these rankings updated regularly?
Yes, we keep our list of the most reliable used cars updated every year. We bring in fresh data from warranty companies, MoT statistics, big fleet surveys and feedback from drivers like you. Reliability can change over time, especially as cars get older or new issues come to light, so it’s important for us to stay current.
By keeping things up to date, we make sure our recommendations reflect the cars you’ll actually see for sale right now. Whether you’re after a small city runabout, a family hatchback or a big-mileage commuter car, our goal is to help you choose a dependable used car that fits your needs. -
Is a reliable used car always cheap to fix?
Reliable cars generally cost less to run because they don’t go wrong as often. But it’s worth knowing that some reliable cars can still be expensive to repair, especially if they’re from premium brands that use pricey parts or complicated technology. So even if a car doesn’t break down much, it might still cost a bit more if something does need fixing.
If you’re trying to keep costs low, it often makes sense to go for a simpler car with fewer expensive gadgets and cheaper parts. That said, buying a reliable car is still one of the best ways to avoid unexpected bills and keep your motoring budget under control. Just make sure you check typical repair costs and any known issues for the specific model you’re considering.
