I don't think the SRT4 can compete with the 350Z in any way other than the price tag/performance aspect
the overall quality of the 350Z is on an entirely different level
the 350Z is RWD the 350Z has more displacement (TT anyone?) the 350Z handles better the power for both is similar...depends on who is driving to decide the race the 350Z has a better quality interior
the 350Z is just on a whole nother level like I said, and much more performance oriented than the SRT4.
the 20-22K price tag of the SRT4 seems to blur peoples vision...if it was 30K not nearly as many people would buy it.
All in all, if I could afford a 350Z I would not even touch an SRT4...I can't see any way in my mind how an SRT4 is someway "better" than the Z.
