A note about Carfax. They are far from accurate. I have seen cars that had 50% of the panels re-painted and obvious body damage with "clean" Carfax reports. My advice is to have a trusted body shop look over any used cars before buying if you don't know what to look for. And use a paint thickness meter if you do know what to look for. This advice is probably more important with certain sports cars then Jeeps but still valid.
