can anyone tell me what year and model these this rim belongs to? i'm thinking its a g35 sedan but not sure. and how much would be reasonable for a set of 4 w/o tires? thanks

those are the early 17" sport wheels for the sedan. I'd say $200 for all 4 wheels w/out tires.

^ Grant is right. Those wheels belong to the 2003-2004 sedan with the Sport Suspension package.

hahaha, I have these rims on my 03 sedan. they look nice but I wish they were larger... time to upgrade to some nice 19" 5 spokes.

Yeah those are what my 04 sedan came with. They are the 03-04 sport sedan wheels. I just sold mine with pretty bald tires for $150 and later got offers of ~$200 so $250 is a good starting number.

i'll see you mine with 2 good tires....
