While you might not get all the info on a CARFAX you do get all the title changes (so you can see how many owners, when and where registered, in states that require inspections it must be listed, the type of title is listed because the state enters that (salvage, flooded vehicle) and it will show recalls for the vehicle--those done and those still open. Less than $50 for a report when you are spending $50k, 100k, or more is a very good investment. Yes personal owner records are good--but they can be suspect too f the owner is being less than honest.
