which is safer to buy (reliability wise) a 1994 300zx car with 84k miles(both) one with turbo and the other is non turbo?

and either one would be a good canidate to have. you will get more power out of the turbo, but when those turbos go they do cost a small fortune.

you can also have very nicely modified na motor but by the same token it wont be as fast as the turbo but still very nice.

either way would be a good way to go. the main thing to look for when buying a Z32 is to make sure that proper maintenance has been performed.

with these cars if they havent been properly maintained you will find yourself spending literally thousands to get them back to there former selves.

good luck with whatever one you choose
