United Kingdom Car Market Data

Carapis provides car-listing data for the United Kingdom’s leading marketplaces — Auto Trader UK, Motors.co.uk and CarGurus UK — through one REST API; Auto Trader UK alone draws over 80M monthly visits, making it the dominant car portal in Britain. The UK is one of Europe’s most consolidated car-listing markets, where a single portal carries the large majority of dealer stock with rich pricing and valuation data.

Dominant marketplaces

• Auto Trader UK — by far the #1 car marketplace, with ~80M+ monthly visits (86.3M Jan 2026) and ~400K-450K live listings across used, new, dealer and private stock. It sets UK pricing benchmarks with its valuation tools.
• Motors.co.uk — owned by O3 Industries + Novum Capital, a major dealer-focused portal and the second key listing network.
• CarGurus UK — the UK arm of CarGurus, applying its deal-rating model to British dealer and private inventory.
• Cazoo — once an online-only retailer, now rebuilt as a dealer marketplace under the Motors network.

UK listings are valued for price, mileage, dealer data and valuation context; vehicle MOT history is a public dataset that pairs naturally with these listings.
