"CHEAP" in the beginning is EXPENSIVE in the end.... ALWAYS start with the best body you can...
When you buy this stuff and open up a can of worms -- and the bids are always "best guestimates" about what needs to be done - and it ALWAYS ends up costing far more. It's just the way it goes.
So unless you're planning on doing all the floors and sills and blah blah blah yourself... That car, to me, is an expensive "1st Gen" not a cheap one...
