I’m new to g35 and don’t know what trim level mine is. RWD, Auto, Spoiler, Splashguards all the way around and is WV2. Sunroof, no nav. I can provide more pictures or answer questions if needed.
I tried looking up what exactly it is but not every car I see has the black underbody like mine and Splashguards seem hard to find for sale (a couple are cracked but I think I’ve settled on deleting them if I can’t find replacements)
Small blurry pictures but it's the best I could find for 2004 sedan, might be worth donating the $2 to that site for high res pictures if it's important to you.
Those are OEM splash guards, rare as hens teeth. I lucked out and bought them when they were clearing them out back in 2007.
Judging by your wheels and spoiler, it looks like you have the "sport package" added onto your luxury or premium package. You will have to crawl under the car and look at the shocks and springs (look for red shocks, springs have a pink dot I believe) also under body panels, but they're harder to find without knowing what to look for.
Also, the black trim a long the bottom was found on the 2003-2004 G35 sedans. The only way to not have that black trim was to get the Nismo package. Google "2004 G35 sedan nismo bumper" for pictures.
