Ill give my .02 here...
IMO if you put any significant amount of miles on your car.. lets say over 1,000. I do not think you will end up with a new car.
Secondly, I took delivery on my car on a sunny afternoon, excited to get the car i took pictures, while not realizing my bumper color was significantly off in the rear, and certainly not perfect in the front. I first realized the problem while looking at the pictures that night, Upon further inspection on my car the next day it was clearly WAY off in the rear.. I have only asked my service manager about painting the rear bumper, he took pictures sent them to Nissan , and they agreed to paint my rear bumper (only thing i really pushed for) with out question. He agreed 100% that it was not acceptable and was as helpful as he could of been. My dealership does have a body shop located directly behind the dealership and they had me drop off my car on a Monday, and it was done Tuesday..
Nissan will do the right thing for you. You may have to agree to repainting the car though. Yes it sucks but its not the worst thing that could happen, as long as it's warrantied and you are happy with the result. I had my old g35 repainted in the front and rear, once to install newer front bumper and i got rear ended and got me a much needed rear 1/4 re finishing, lol. It came out awesome. The Infiniti paint was not all the greatest. The Red faided and the bumpers definatly didn't hold up too well to rocks/bugs, the repaint came out better than factory without question.
My girlfiends audi paint is without question far superior in quailty to Nissan Paint, it just holds up ridiculously well.. its a 1999 with 154k miles and it's rarely washed. It is Pearl White and when you clean it the paint looks mint on the entire car. The clear is amazingly strong and resistant to chips and scratches.
it is what it is, just get it fixed asap
The paint quality on the 370z seems very good to me, but in my case, my front and rear bumper color was way off and someone had to stamp this car as good to go when it had obvious blemishes.
Before:
After:
clear is as strong as factory in the rear, and the paint matches 99%. I have zero issues with this outcome and it was repainted.
