problems with 3000gt

i was just wondering, are these cars costly to maintain? and do they have any common problems? i was looking at some 300z's and found out that a tune up on them is $400. is it the same with the 3000gt?

Yes - the 3000 is like any other expensive sports car. They're going to cost more to maintain.

yes, they can get costly at times to maintain. The N/A's are more reliable than the twin turbo cars. The main thing to watch out for is the 60K tuneup which can cost upwards of $800.
