The 300z is my fav out of all them, but I find all the Z series to be just ok in gt5. They are all decent and do everything fine, but it's never great, it never gives you that "OMG this car is god feeling". Even for drifting where in real life there are a lot of Z models I turn one into a drifter and it's good, but my rx-7 beats it, my viper beats it, my... Etc. That's what kinda makes me mad cause every model is slightly worse than something in it's class. But in the end I still love the 300z with it's twin turbo engine, it's pop off roof, it's low ride height and it's 90's sports car looks.
