im looking to buy a 1975 280Z, the guy wants to sell it but doesnt kno how much, its in good cond., little rust, newer paint, good interior, 4 spd manual, and has 75000 origional miles. all that it needs is a rear bumper, how much would be a fair price, i can also get a 350 chevy out of a 1997 Camaro SS with 53,000 miles on it, he wants $600 for the engine, harness and the computer, is that a good price for both?
