RE: I found a 1970 Dodge Challenger in a local junk yard, how rare is it?
If you can get back for a closer look and record the VIN, that would tell us what it is and how rare. Not sure how much luck you'll have with a nut like that owning the property, though. The VIN, by the way, is on the driver's side top of the dash by the windshield, if you can get close enough for a look.
