Cheapest car to restore?

[TreySmith]

Just curious as what would be the cheapest to restore and pull the most profit.. Being a high school kid, Challenger's and first gen. Camaro's are out of my league..

So far I have seen solid late 70 f body's in the $2000 range. Also seen Cougar's in this range also..

Is there any other cars I should look at? I have found one nice T/A I am about to jump on but I would like some opinions on what direction I should go..

Also, what would it cost for a complete interior resto if I did everything myself? $1000?
