The Nissan 350Z saw a few changes for 2005, including standard tire pressure monitors across the board and a more powerful engine in some models. In addition, Nissan released the Anniversary Edition, celebrating 35 years of Z cars, and another new trim, the Grand Touring edition. The 2005 350Z came in seven separate trims, with a few of those available as convertibles. The trims include the base model, the Enthusiast and Enthusiast convertible, the Anniversary Edition, the Touring and Touring convertible, the Grand Touring convertible, the Track, and the Performance. The entire lineup shares a 3.5-liter V6, but while the base, Enthusiast, Touring, and Performance models retained the old 287 horsepower, the Aniversary, Grand Touring, and Track models upgraded to 300 hp. Fuel economy for all models is about 20/26 mpg. The 2005 350Z has many fans, who like the car's looks, handling, and performance, as well as the fact that it is quite affordable considering all the true-sportscar features it comes with. One frequent complaint is the poor rear visibility. Other drivers complain that the ride is bumpy, but many contend that is par for the course with a sports car.
