What about a 4-door '73 Dart? Just took a look at it today, could probably get it for $800. Slant-6 runs but has a knock on the bottom end; owner took the head off and redid the top end thinking the noise was there but I heard it run and it sounds like a rod knock. Other than that it is in GREAT shape, no rust at all and even the vinyl top is still there. Interior is super clean as well.
