the only thing i missed from the Z was the transmission. I had the 6 speed manual...and went to my SRT-10 Ram which was automatic (needed a quad cab at the time)...now that i got the EvoX GSR...i'm loving every second of it. Like someone said on the evo forums...if u want to mod, get a GSR. The MR's transmission can hold a decent amount of power...not alot, but decent amount...but when it breaks...it breaks hard (so i've heard). Plus you wont loose as much drivetrain power with the 5 speed manual. And also the GSR costs less. Trust me, get the Evo...i got rid of the Z for the same reason...wasnt practical at all. And i dont regret it one bit.
not sure down there in the states..we pay more in Canada for cars. I'm guessing new EvoX's are around 35-40k...so used it would probably be between 30-35k...depending how used. Evo's are expensive as hell but they hold a really high resale value. I can tell you straight up...the Evo is better then the 370z imo.
