Web Service for Automotive Marketplace

I am looking for a web service to create an automotive marketplace. This marketplace will be for a new enterprise that I am starting. I need this platform to have the functionality of listing, selling, and deal-making, but not the additional features of scheduling services and reviews and ratings. The design of the marketplace will not need to be extensively customized; rather, I am looking for a basic template that can be easily navigated and understood by any user.
