Questions about buying 1970 Barracuda (from a Camaro guy)

I don't have much info for you (though there are roughly 2,028,297,057 other guys on here that will) 13,000 sounds high for the car you described. If there's a good deal of rust, the interior is rough, and the engine needs a rebuild, then that sounds more like a 7,000 deal unless there are some options we aren't yet aware of. Technically the car is an E-body since it is a post 1970 Barracuda, but I'm sure plenty of the boarders will have some tips for you.
