Im about to buy a 92 300ZX...150K...the car had not been started for a while. So finally after starting, the tranny works fine...shifts 1-5 smooth BUT, it does not rev past 2500rpm...what could be the problem? I didn't wanna get into a pocket drainer...I love these cars but my pocket has other loves too....any ideas what it could be? is it a good risk to get into a car such as this? if there's anything I should keep a heads up on, what would it be regarding this car? I noticed how friendly and the 'willing to help' attitude everyone posesses on here so in advanced responses are very much appreciated.....
