In the personal car buying "business," it's a difficult and long process that requires sifting through thousands of car offers to filter out the cars that don't meet my expectations or requirements.
I'm a regular Amazon shopper, and I find the Recommended To You page and wishlist feature very useful. It would be great to have this feature when shopping online for used cars. However, none of the major car classifieds sites have an account system with these features.
Does anyone use anything like this?
