Autotrader is the clear sector leader but the Emap-owned Parkers Online continues its own rapid growth as a service. The site, which aims to create a community of car-owning web users through a blend of car information and user groups, launched in January 1999 with 1.3 million page impressions.
It offers details on pricing for most UK used cars and a service for car owners that includes insurance advice and a guide to selling cars.
Advertisers include Lombard Direct, Ford, Tesco Loans and KLM.
