Update - Bought a Demon project - WWYD?

I am currently Moparless (other than my '80 D150 daily driver/beater) and it is driving me nuts. So, even though it is really not in the budget, I am going to look at a 72 Demon this afternoon. Car has been on CL for about a month and a half. I initially contacted him a month ago and he seemed eager to sell it.

Here is the ad copy:

1972 Dodge Dart demon For Sale!!!!!! This is a restoration model and it needs to be put together. Currently has a slant six motor in it; however I also have a 318 bore out 30 over to go with it and the transmission too. This could be a fun car for someone. Don't hesitate to call 305-308-2771 for further information about this wonderful project car. If you need to see pictures just call and I will text or e-mail them to you. This car will not last $ 1,000.00. The wife says it goes or I go, so best offer is welcome!!!

He sent me some pics and it looks to have some of the usual rust issues but overall not too bad. No front seats and I don't know why the /6 does not run. He says the frame rails are in good shape.

Of course, I don''t plan on paying full price - may even offer for him to keep the 318 since I'd go either 5.9 Magnum, big block, or modern Hemi with it anyways if I keep it.

What do you guys think? Can I go wrong with this car if I get it for $750 or so? Was thinking maybe I should fix the rust, give it a nice paint job and maybe flip it so that I can get myself a better truck for myself and the family...
