2006 Nissan 350Z Convertible Touring 2dr Convertible (3.5L 6cyl 6M)
It's been fun, but....
 I've had my  manual 2006 350Z Touring Convertible for 4 years, been fun but expected higher quality & reliability for $40k.  Good-Fun car to drive, great styling, always turns heads. Good power, good mileage.  I don't drive it very hard, it's a commute vehicle, but have pushed the speed and cornering a few times and had a blast.  Bad-The stock tires had to be replaced after 26k miles ($700).  Constant reliability problems (not including small items under $50), in a short 4 years, I've experienced a cracked drive shaft, cracked convertible top, bubbled coating on both door handles, failed convertible top mechanism, belt replacement after 2.5 years, interior paint degrading & peeling off
