Hotswap.com has several features which provide an interesting way for users to find a used car or sell theirs. Individual sellers make listings for no fee while dealers pay a small fee per listing and pay for more advanced listing-tracking software. Ajax search tools make it easy for users to search for vehicles based on color, location, model, mileage and price range. Offers can be made directly over listings on the web, and users can ask questions about vehicles to owners. Listings can also be transferred over to other sites and embedded there.
