5 Best Used Car Dealerships in London (2026)

Independently ranked by our review of ratings, reviews and reputation · How we chose

Talise Sterling
By Talise Sterling, Goods and Shopping · ✓ Data verified July 2026 · 9 min read

Buying a used car in London usually means choosing between a supermarket forecourt with thousands of cars and a small independent where the owner remembers your name. The used car dealerships on this page have racked up nearly 9,700 Google reviews between them, and the top pick alone, Car Planet Barnet, carries 4,170 of those at 4.7 stars. That kind of volume at that rating is rare, and it's worth understanding why before you hand over a deposit.

Short answer: Car Planet Barnet leads on scale and score: 4.7 stars across 4,170 reviews, with over 2,000 cars in stock and a 150-point inspection on every one. Big Motoring World Wimbledon (4.5, 3,959 reviews) is the other supermarket-sized option. For a smaller, more personal buying experience, KEECARS in Clapton holds the highest rating on this page at 4.8, built on 145 reviews.

Car Planet Barnet

4.74,170 Google reviews

Car Planet Barnet is one of London's largest used car supermarkets, with more than 2,000 cars on the forecourt at any time, sourced from trusted vendors and verified private owners. Every car goes through what the dealer calls a National Prep Centre, with a 150-point inspection, MOT, and service where needed, before it reaches the lot. It also offers finance from 12.9% APR and a £99 refundable reservation fee to hold a car for 48 hours.

What people praise

  • Reviewers repeatedly praise individual salespeople (Zakka, Ishra, Waris) for clear, unpressured explanations
  • Huge selection means more chance of finding the exact spec you want
  • 12 months of free roadside assistance included with every car

Worth knowing

  • A cluster of one-star reviews describe long waits, unclear paperwork, and vehicles arriving with missing items or fuel
  • Multiple reviewers say documentation between branches (Watford to Barnet) got lost, so double-check your car's full history before signing

Our take: The scale and the 150-point prep process are real advantages, but the negative reviews cluster around a specific pain point: paperwork and communication on the day of collection. Ask for full documentation upfront and inspect the car in daylight before you drive it away.

Big Motoring World - Wimbledon

4.53,959 Google reviews

Big Motoring World Wimbledon is a large-format used car dealer with thousands of vehicles in stock across popular makes like Audi, BMW, and Land Rover, plus its own finance arm.

What people praise

  • Reviewers single out specific salespeople (Bili, Syed, Raphael, Josh) for patient, unpushy service
  • Handover team gets separate praise for making the final pickup smooth
  • Wide stock across electric and combustion models

Worth knowing

  • One detailed review describes corroded brake discs and missing jacking plate covers found on independent inspection after a stated 200-point check, resolved only through the Motor Ombudsman
  • Get any car independently inspected before you commit, especially on safety-critical components

Our take: Most reviewers leave happy, and the volume here is genuine. The one serious complaint is worth taking seriously precisely because it's about brakes, not cosmetics, so build in an independent check as a condition of sale if you can.

Deals On Wheels London

4.61,120 Google reviews

Deals on Wheels London is a used car dealer on the Harlesden High Street with a strong track record for fast, low-friction purchases. Reviewers consistently name individual salespeople who walk them through financing and paperwork without pressure.

What people praise

  • Reviewers highlight quick, friendly service from named staff (Zack, Ali, Ahmed)
  • Warranty and contract details explained clearly, according to multiple buyers
  • Good option for buyers who want to move fast on a budget car

Worth knowing

  • One reviewer says the lot is packed tight and some cars looked dirty or parked awkwardly
  • Photos online may flatter a car more than it looks in person, so see the actual vehicle before you decide

Balham Cars London Ltd

4.4321 Google reviews

Balham Cars London runs both a used car dealership and an on-site MOT and repair garage in Tooting Bec, which means customers can keep coming back for servicing long after the sale. Several reviewers describe multi-year relationships with the business, returning for MOTs, repairs, and eventually their next car purchase.

What people praise

  • Multiple reviewers describe returning for years for servicing after buying their car here
  • Owner (Vai Raj) personally follows up on issues, including waiving costs outside warranty in some cases
  • MOT centre on-site means one less garage to find

Our take: The dealer-plus-garage model shows up clearly in the reviews: people who bought here keep coming back, which says something about trust that a one-off transaction can't.

KEECARS

4.8145 Google reviews

KEECARS is a used car dealer and leasing service on Clapton Common with the highest star rating on this page. It's a smaller operation than the supermarket-scale dealers here, and reviewers describe a more personal buying process, including remote sales for buyers outside London.

What people praise

  • Highest rating on this page, built on real reviews rather than a small handful
  • Reviewers describe a low-pressure, detail-oriented sales process
  • Handled remote purchases for buyers as far as Manchester, according to one review

Worth knowing

  • Smaller stock than the supermarket-format dealers here, so the exact car you want may not be on the lot

How we scored these dealers

We rank on live Google data: star rating, how many customers left a review, how that rating holds up as volume grows, and how recent the reviews are. A dealer with thousands of reviews at 4.5 and one with 150 reviews at 4.8 are both legitimate, just at different scales, and we spell out that difference in each write-up. No dealer can pay to change these numbers.

What used cars cost in London (2026)

Used car pricing in London depends heavily on make, mileage, and finance terms rather than the dealer alone. Several dealers on this page publish their own finance rates (Car Planet quotes from 12.9% APR representative), but we don’t have an independently verified, dealer-neutral price sheet to cite here, so we’re not printing invented figures. Compare like-for-like finance quotes across at least two dealers before you sign.

Used car dealerships across London

This list spans north, south, and east London: Barnet and Clapton Common to the north and east, Wimbledon, Tooting Bec, and Harlesden to the south and west. If you’re searching for a used car dealership near me from anywhere in Greater London, you’re within a reasonable drive of all five, and most run seven-day opening hours.

What to ask before you buy a used car

  • Can I see the full service history and a fresh HPI check?
  • What’s covered under warranty, and for how long?
  • Can I have the car independently inspected before I commit?
  • Is the reservation fee refundable, and under what conditions?
  • What’s the true APR and total cost if I finance through you?
  • Will I get all keys, the V5 logbook, and complete paperwork at collection?

Frequently asked questions

Are these rankings paid?

No. Rankings come from public Google data. A business can pay to be a Featured Partner (badge and top placement), but that never changes another business’s score or position.

How did you choose these dealerships?

We pulled real Google Business listings for used car dealers serving London, then ranked them on rating, review volume, and how consistent that rating stays as more customers weigh in.

How often is this updated?

We last verified these numbers in July 2026 and refresh the page periodically as new reviews come in.

Should I get an independent inspection even if the dealer says they’ve checked the car?

Yes. Even dealers who advertise a multi-point inspection can miss issues, as one detailed review on this page shows. An independent check before you complete the purchase costs little compared to the repair bill if something is missed.

Is a bigger dealership always the safer choice?

Not necessarily. The largest dealers here have the most reviews and the widest stock, but the highest star rating on this page belongs to a much smaller operation. Scale buys selection, not automatically peace of mind.

The bottom line

If you want the widest stock and don’t mind checking paperwork carefully yourself, Car Planet Barnet or Big Motoring World Wimbledon will have the car you’re after. If you’d rather deal with the same few people from purchase through years of servicing, Balham Cars or KEECARS are the better fit. Whichever you pick, get an independent inspection before you sign.
