About us:
At MOTORS, we like to say that we know MOTORS!
Millions of people come to us every month to find their next car, because we keep the car search process simple. We have hundreds of thousands of used cars listed for sale by dealers nationwide, and guides, advice, tips, and reviews to help buyers find the right one.
We don’t just help consumers, though. For our dealer partners, we offer a unique advertising ecosystem that enables them to showcase their cars to buyers across some of the UK’s largest car search sites, including Motors, Cazoo, eBay, Gumtree, and Parkers.
In 2024, Cazoo became part of the MOTORS family when we purchased the brand and launched the Cazoo app. So, it’s an incredibly exciting time for Cazoo as we look to transform one of the UK’s most well-known automotive brands into one of its leading automotive marketplaces.
MOTORS is also the proud sponsor of The British Motor Show and the Official Automotive Marketplace partner of Premier League club Brentford FC.
