I too was ready to buy my Z in late May and my dealer offered a 1000.00 discount on an 03. but he told me that I could order an 04 in june and I would take delvery in September.
I decided to wait, in sept. 6 i got my 04, I am glad I done that cause here we are almost a year later and my car is til to year date.
Not to mention that I don`t have the tire feathering problem or tranny problem, then I only have like 4500 miles on it.
I would wait!!
