I had a 2004 350Z and a 2005 G35 Coupe before I got the 370Z, and I must say, none of them ever had any problem...I don't recall ever having to take my 350Z or G35c in for warranty work...there were problems with the cluth on the 2003/04, but I never had problem with mine..eventhough there were problems, they were all covered under warranty...I think there was a problem with the 6MT tranny with the 2003s and some 2004s, but that was covered under warranty and they caught that right away (just like the tire feathering issue) and replaced all the affected vehicles....I did get a buddy of mine to replace my tranny and clutch for me just for the hell of getting a new tranny and clutch after 30k miles...hehehehe...he wrote it up as a claim and I got new tranny/clutch for free..hehehe....
well, I guess there's one small problem with the 350Z that I don't know who to blame on...and that the car just don't stay intact when getting split by a tree...but don't let this discourage you from buying a Z...case in point:
