the 80s 300zxs are UGLY, rust buckets, and have no power, and the 90s 300zxs are ok looking, have mad electrical problems, and have a lot of power (turbo of course). Also one of the most complicated engine bays ive ever worked on/seen, besides the TT 3000gt lol. But if you dont mind doing lots of work everytime something breaks, go for it. The + that ill give the z32 is that its almost as fast as a mk4 supra and much cheaper, so it isnt that bad of a deal.
