Questions about buying 1970 Barracuda (from a Camaro guy)

Thanks to all of you that left me advice. As I said in the post, I know next to nothing about Mopar. Thanks to those of you that didn't make fun of me! :) I figured that he should run away from this car, but I just wanted to make sure. He is rather impulsive and I think that last Barrett Jackson auction might have made my brother lose his mind. =)

I did find this lost gem in a local junkyard:

The drivetrain is intact but it definitely needs some TLC. I don't have the time or money to fix it up now (and I have to finish the Camaro first), but I can't bare the thought of all these old classics going to the scrap pile. There is a free spot for it in my grandpa's barn. Think it would be worth $300-500?
