Done a bit more on it now, had some troubles exporting, Maya kept crashing, I think it may have to do with the poly count.

Updates:

Added GT-R badge on the front, still needs the one on the back
Added windshield wipers
Added license plate mounts on the back
Added trunk key hole
Reworked the tires; made the sidewalls thicker, and the wheels smaller
Finished the brake lights
Tweaked a few things

I think that's it, could be more. Pretty tired though, bedtime for me.
