This is an awesome car. However, I am very surprised that I have not heard anything about the ride quality. If you are thinking of buying a z, do it, but beware the ride in the city is harsh. I live in the city, but most of the car dealers where I live are in more suburban areas. Thus, my test drives were on nice smooth suburban roads. The first time that I drove into my office downtown I was shocked by the ride quality, severely stiff and unforgiving (I have the 18's, which probably don't help). Road imperfections are often jarring and I am concerned that the car will develop rattles over time. I have actually resorted to driving my pathfinder into work most of the time in an attempt to keep it tight.
That said the car is awesome for weekends and days when I just can't walk by it and not drive it. The car is fast, it will hit 100 in the blink of an eye and the same suspension that I have criticised is masterful when you have a chance to push it a little. The car meneuvers with surgical precision. The gas mileage is exceptional too. I love the car, but after all of my research I was surprised that I hadn't read about the harshness of the suspension.
Finally, the car gets lots of attention from girls downtown which makes the bumps less important. I still would have bought the car.
Fast, comfortable, beautiful, harsh ride on less that perfect roads.
Well, what do you expect from sports car with 18" rims in the city? Of course the ride will be rough, unless roads where you live are really good (which is the opposite for me).
