For the money, there aren't too many performance cars that can touch the Z. The non-turbo and turbo model have plenty of power, and can outperform any other car in its class. With only an exhaust modification I have dropped the 0-60 times to just over 6 seconds for the non-turbo.
The handling is similarly amazing, Nissan developed 4 wheel steering for this car nearly 14 years ago, and the car handles like it's on rails. I have heard some complaints about the handling on wet surfaces, however I have yet to encounter any problems in wet weather.
My 300 ZX has been family owned for nearly 10 years, other than some regular maintenance the car runs flawlessly. Aside from some AC work I have no complaints at all with this quality machine. I know many owners with well over 150,000 miles on their engines.
The interior is simple, and well laid out. There are no un-needed gauges, the tachometer and speedometer are nice and large (as they should be on a sports car). The AC/Heat controls are within easy reach while driving. The seats are comfortable and provide proper support, although on a long drive they become a bit uncomfortable. For a car this size, and in this class there really is a lot of trunk space. The only minor complaint I have with the interior is that the center controls (namely the radio) seem just out of reach while sitting back in the seat.
The exterior of the car is very well done. I have kept my Z in pretty nice shape, and not many people would suspect the car is 14 years old. The lines are still modern, and the wide girth and low profile only add to its appeal. I would take a new 300 over the newer 350.
All in all my experience has been a good one. I have no problems at all with this car. Full synthetic oil changes, and premium fuel can be a detriment; but when you get behind the wheel all is forgotten. I can't wait to get my hands on a twin turbo.
