I really like my 04 350Z Enthusiast model. Got CAI and Nismo Bronze 19 wheels, looks good.
I would follow with agreement on most of the issues/concerns from those that have first hand experience. I did a similar recon mission of FAQ about the 350's before diving in, and got wildly differing opinions/stories/myths about these cars.
I cannot speak about the later 'Rev-up' motors, however my 04 350 seems to be 'normal'
-Shifting into 2nd is an issue for the new driver, but you learn your new car and shift it the way it likes.
-Oil consumption isn't an issue for me, knock on wood.
-Seat bolsters are not the best quality. Fabric seems to wear easily for the time spent in the seat. I am almost worn through along the seam in the bolster at 44K (started at 20K)
-Fun track car, although my transitional shifts from left to right (especially at autox's) will make my lower seat cushion drop out unexpectedly. I have a fix for this and am not readily sharing weekend events with my Nissan Stealership.
-Front tire wear. Fixed with new alignment, toe set at 0. I bumped a curb (enough to curb the rim :( ) and that REALLY whacked the front toe! I wore out a set of Nitto INVOs in 15K before I realigned and found out it was at 1/2 inch toe in!!!
-Very comfortable on long drives. I put 5600 miles in 5 weeks last summer with a drive out to IA from CA and a couple of weekend car shows.
Good stuff, no regrets, except for the payments... This replaces a Contour SVT that was totalled and paid off...
Ohhhh, styling (if it matters) I really prefer the beltline of the new 370z as the 350z definitely looks like the next version of the 300zx with the straight beltline. I am a S30 (240Z) owner and would rather have seen the resemblence from the older z's than the last generation.
YMMV,
