first up, i would have to say, 1980 pontiac gran prix. i had one a while ago, pulled the engine and trans out, put in a nice 350 and 350 trans.......fixed the rear frame rails (they always rot out), and i had it ready for paint when i sold it. it was orange with a black top and black interior, it was really sharp when i was done.....i added the buckets and console/shifter from a monte carlo to it as well. i miss that car!
im still thinkin aout the other 4......
cheers
