If you want some laughs, go read some of the Yahoo car reviews on the GT500. I must say though that reading up on the filter problem has definitley helped me understand why some of these folks are just not happy with their cars. Going from a 13.4 to a 12.8 is a HUGE difference with any car as most people here well know. I'm sure the people complaining about the car not being fast on Yahoo are all experiencing the filter problem.

 

That's one possibility. Another would be not being informed or having illusions of what the car isn't.
