I am new to the Z world and I would like to get some advice reguarding buying a Z car. First of all, there are 3 cars for sale that I am looking at. 1) 1972 DATSUN 240z excellent condition, new paint, floorboards, tires, brakes, rollbar, additional new performance parts available, car runs great $6000CDN 2) 73 DATSUN 240Z, brand new 280 eng, flat top pistons, 5 spd, perf body, all met red, eng bay painted, AirCared, drive it & say wow $8000CDN 3)74 DATSUN 260Z, 97,000 orig mi, AirCared, no rust, frame & flr, solid, rcnt exh, brks, CD sound, tires, orig 6 cyl dual carbs, 4 spd, body stripped & repainted red $6500 cdn I am wondering which one sounds like the best deal. its all in canadian dollars and they are western cars, british columbia, so there is minimal rust. I am wondering what the difference, if any, between a 72 and 73 240z is? I am mostly interested in the 73 because of the engine work and the 5 speed, but I need help in what to look for. are there any tricks in trying to figure out if a Z car is a lemon? any help would be great.
