I'm 17 and I want a 300Zx. I'm probably gonna get a 90 or 91 N/A. I've heard that the engine will last forever and that its a high quality car. If any of you have advice on how much I should pay, and performance mods, and things to look out for, etc.... Please share your expertice. thanx.

For NA Z around 90/91 you should not pay more than 8K...look also for low mileage.

As for performance mods...you might want to check out...this will give you some ideas of what to do...ie intake/headers/exhaust/ecu.
