Find Out What People Paid For Their Cars is a site dedicated to bringing you previously secret information, the actual price people are paying for their cars. Just select the make and model and the site spits out the info. The database gets filled by reader-submitted reports. There’s no guarantee that everything is 100% accurate, but it can at least give you a better picture of what you you can reasonably expect to pay…and negotiate for.
