i dont agree with that at all.
i had a 350 for 3 years and looked at other cars to "upgrade" there was nothing out there for the price, quality, spec, drive, power ect....
i absolutely love my 370z.
i think that its enough of a change:-
looks
power
interior
spec
its totally different to drive too. (i have done wales in both)
i love it!! better that TT or Z4 ect!!
......"not for everyone"
I think Jay might agree with me!
