interesting idea. Definately one to develop if you plan on making any money on it, but it should be as a hobby and not pruely for profit coz it will take alot of work to do and i don't think the income will be great (do car companies do affiliates???)
Theres a company in the UK called corporation365, which is a net firm with its fingers in alot of pies...you might want to try them with the team365.com name.
