Buying a used car online is now the norm in the UK, and there is a platform for every kind of buyer — from vast nationwide marketplaces to fully-online retailers that deliver to your door with a money-back guarantee. The catch is that more choice also means more risk: clocked mileage, undisclosed write-offs (Cat S/Cat N), outstanding finance and expired MOTs are all out there.
This guide ranks the 10 best websites to buy a used car in the UK, explains who each one is best for, and shows you exactly how to protect yourself before you pay. Whatever site you use, running a VIN/history check with ProVinCheck before you hand over money is the single easiest way to avoid an expensive mistake.

The 10 Best Used Car Websites in the UK
Rank 1: Auto Trader
autotrader.co.uk
Launched in 1996, Auto Trader is the UK's largest and most recognised car marketplace, with hundreds of thousands of listings from both dealers and private sellers. Detailed listings, price-indicator labels, MOT data and finance tools make it the natural starting point for almost every UK used car buyer.
Pros
- The biggest inventory in the UK, so you can almost always find your exact make, model and trim.
- Price-indicator labels and running-cost calculators help you judge a fair deal and budget for ownership.
- A mix of dealer and private listings, with vehicle checks and financing built in.
Cons
- Private sellers pay to list, and private sales carry more risk than dealer purchases.
- The sheer volume of listings can feel overwhelming for first-time buyers.
Rank 2: Motors.co.uk
motors.co.uk
Motors.co.uk is a clean, easy-to-use marketplace weighted towards trusted dealerships. Intuitive filters and its 'Smart Search' feature help match cars to your lifestyle — fuel economy, family space or performance — making it a strong, lower-risk alternative to the biggest sites.
Pros
- Mostly dealer-backed listings, often with warranties for added peace of mind.
- Fast, intuitive search with a helpful 'Smart Search' lifestyle-matching tool.
- Good coverage across the UK with clear pricing to compare.
Cons
- Fewer private-seller listings than the biggest classifieds.
- The dealer focus means fewer very cheap or budget cars.
Rank 3: heycar
heycar.com/uk
heycar lists cars exclusively from vetted dealerships, with a focus on younger, low-mileage vehicles that come with a warranty. Every car is handpicked to meet quality standards, making it one of the safest and most reassuring ways to buy a used car in the UK.
Pros
- Dealer-only, quality-checked listings, typically low-mileage and warranty-backed.
- No private sellers, so less risk and a more professional experience.
- Simple, clean interface that is quick to search.
Cons
- Smaller inventory than Auto Trader due to the quality focus.
- Fewer older or budget-friendly cars for cost-conscious buyers.
Rank 4: CarGurus
cargurus.co.uk
CarGurus uses market data to rank every listing as a fair, good or great deal, so you can spot value at a glance. It aggregates cars from both dealers and private sellers and includes dealer ratings, making it a powerful tool for data-driven buyers.
Pros
- Deal-rating algorithm highlights good and great value against the wider market.
- Broad filtering across dealer and private listings.
- Dealer reviews and ratings help you judge who you are buying from.
Cons
- The volume of listings can be overwhelming for newcomers.
- Less emphasis on certification than dealer-only platforms; private cars may have no warranty.
Rank 5: cinch
cinch.co.uk
cinch sells inspected used cars entirely online, with home delivery, a 90-day warranty and a 14-day money-back guarantee. Fixed, no-haggle pricing and doorstep delivery make it one of the most convenient ways to buy without ever visiting a forecourt.
Pros
- 100% online purchase with home delivery across the UK.
- 14-day money-back guarantee and a 90-day warranty for reassurance.
- Fixed, transparent pricing removes haggling and pressure.
Cons
- No test drive before delivery — only the return window as a safety net.
- Convenience and guarantees can mean slightly higher prices, and fewer older cars.
Rank 6: Carwow
carwow.co.uk
Carwow flips the usual process by letting vetted dealers make offers so they compete on price, alongside expert reviews to guide your choice. It is a low-pressure way to compare used and nearly-new cars without haggling in person.
Pros
- Dealers compete for your order, which can sharpen the price.
- Vetted dealer network reduces the risk of dodgy sellers.
- Expert reviews and comparisons help you choose the right model.
Cons
- Dealer-only, so no private-seller bargains.
- The process can take longer than instant-buy online retailers.
Rank 7: PistonHeads
pistonheads.com
Founded in 1999, PistonHeads grew from a much-loved car-enthusiast forum into a marketplace that shines for high-performance, luxury and classic cars. Its active community is a genuine asset when you want advice on something special beyond the everyday.
Pros
- A go-to for performance, luxury and classic cars that are harder to find elsewhere.
- Knowledgeable community and forums to research your purchase.
- Varied listings from everyday runabouts to rare collectibles.
Cons
- Less emphasis on dealer-backed warranties and quality assurance.
- Not ideal for budget buyers, and the interface feels dated.
Rank 8: Arnold Clark
arnoldclark.com
Founded in 1954, Arnold Clark is one of Europe's largest independent car retailers, with a vast used and new inventory across a nationwide branch network. Its long-established reputation and strong after-sales service make it a dependable, no-surprises choice.
Pros
- Enormous selection spanning budget to premium models.
- Established, trusted retailer with strong after-sales support and warranties.
- Nationwide branches make click-and-collect and servicing easy.
Cons
- Dealer-only, so no private-seller options.
- Less room to negotiate than with small independents, and buying often involves a branch visit.
Rank 9: Gumtree Motors
gumtree.com
Gumtree Motors is a busy classifieds platform with a huge range of budget-friendly cars from both private sellers and dealers. Its local focus and low prices make it a great place to find a cheap runabout — provided you do your own homework on every listing.
Pros
- Plenty of affordable, negotiable private-seller cars.
- Both private and dealer listings for extra choice.
- Strong local focus makes viewings and quick pickups easy.
Cons
- Private sellers are unvetted, so listing quality varies widely.
- Little to no buyer protection, and basic search tools.
Rank 10: Motorpoint
motorpoint.co.uk
Motorpoint is one of the UK's largest car supermarkets, specialising in nearly-new and low-mileage vehicles at competitive prices. You can browse and buy online with home delivery or collect from a branch, backing a strong-value inventory with warranties and a money-back guarantee.
Pros
- Great value on nearly-new, low-mileage cars in high volume.
- Flexible buying: fully online with delivery, or reserve and collect in branch.
- Warranty and money-back guarantee for added confidence.
Cons
- Focus on newer stock means fewer older, cheaper cars.
- Fixed pricing leaves little room to negotiate.
A smarter way to shortlist
Search two or three platforms in parallel — one big marketplace (Auto Trader or Motors.co.uk), one dealer-quality retailer (heycar or cinch), and a value-checker like CarGurus. You will quickly see the true market price for your car and spot which listings are genuine bargains and which are too good to be true.
Buyer safety checklist
In the UK the responsibility for checks is on you — especially with private sales, where there is no automatic refund. Work through this checklist before you pay. Tick items off as you go.

Run the history check before you pay
A used car history report built from the VIN is the fastest way to expose problems a seller may not mention: outstanding finance, insurance write-offs, mileage discrepancies and stolen markers. It takes minutes and can save you thousands. Check a VIN with ProVinCheck before you agree to buy.
How to avoid scams when buying a used car in the UK
Most sellers are honest, but online marketplaces attract fraud. Knowing the common tricks makes them easy to avoid.
Classic red flags to walk away from
- A price far below market value. If a clean, low-mileage car is suspiciously cheap, assume there is a catch or a scam.
- Pressure to pay a deposit before viewing. Legitimate sellers let you inspect first. Never send money to "reserve" a car you have not seen.
- Requests for bank transfers, gift cards or "escrow" links. These are hallmarks of fraud. Pay in person once you are satisfied, using a traceable method.
- A seller who "cannot meet" or is "away with work". Vehicle-in-transit scams rely on you paying before delivery. Insist on an in-person handover at the V5C address.
- Reluctance to share the VIN, V5C or MOT details. Genuine sellers have nothing to hide. No documents, no deal.
The most common financial risks in the UK are not outright theft but mileage fraud (clocking), undisclosed insurance write-offs and outstanding finance — problems that are invisible in photos and easy to miss on a quick viewing. That is exactly why a VIN-based history check plus a careful inspection are worth the small cost.
Don't inherit someone else's finance or write-off
Outstanding finance, clocked mileage and hidden Cat S/Cat N write-offs are the most expensive surprises in the UK used car market — and none of them show up in the photos. A ProVinCheck report reveals them all in minutes.

- Accident & damage
- Title & ownership

The bottom line
The UK used car market is huge and mostly online, so the platform you choose matters less than the checks you do before you pay.
