PistonTraders is an independent UK used car search engine that helps people find and compare vehicles advertised by dealers. It indexes live stock directly from vetted UK dealer websites and links users to each vehicle’s original dealer listing, so shoppers can review details and contact the seller directly. The service is free to use and does not sell cars or charge for paid placements.

Users can search a large, regularly updated selection of vehicles by make, model, keyword, fuel type, price, mileage, year, location and other criteria. Listings cover a wide range of cars and vans, from affordable used vehicles to newer and premium models. PistonTraders presents information such as price, mileage, transmission and fuel type, with further details available on the dealer’s site.

The brand also provides a live JSON API for AI agents and other approved automated clients seeking structured vehicle data. Its API supports vehicle filters and pagination; PistonTraders advises clients to use live API responses and include the original dealer listing link.
