Quick Comparison: Best Car Selling Websites UK

SwapAuto

Best for: Affordable private selling with built-in trust

SwapAuto is designed specifically for private sellers who want a simpler, safer, and more transparent way to sell their car online.

• £24.99 one-time listing fee
• Your advert stays live until sold
• Access to over 500,000 buyers
• Free vehicle background checks included
• MOT history included on every listing

One of the biggest advantages of SwapAuto is buyer trust. Every listing includes important vehicle information that helps buyers feel more confident when making enquiries.

This can help sellers:

• attract more serious buyers
• reduce time-wasters
• improve overall selling confidence

Pros

• Transparent pricing
• No relisting fees
• Trust-focused platform
• Vehicle verification features included

Cons

• Smaller overall brand awareness than AutoTrader

AutoTrader

Best for: Maximum marketplace exposure

AutoTrader remains one of the largest and most recognised automotive marketplaces in the UK.

Many sellers choose AutoTrader because of its:

• large audience
• established reputation
• strong search visibility

Pros

• Huge buyer audience
• Trusted brand
