yea its kind of old, but none the less. Our G35x's kick ass
I just got a 04 RWD loaner.
I can feel the weight difference...but still feels slower (04 = 20 less hp) The biggest difference is the suspension. Car sits much lower, and has much less body roll...I want my car lowerd now...badly.
The tranny is much better. The car had 100k miles on it...and under heavy acceleration, the car doesnt go CHUNK like mine in tiptronic mode (maybe mine is not broken in?). The rev matching is a definite plus in the 05. The 04 is definietly sipping less fuel tho....
