I think all the colors look good on a good car.. like the Z, not crazy on the "magma" red. Looks like you got the nail polish/fire engine red, can't really go wrong with that. All my prev cars and truck have been either red or black so i was shopping for a white or gunmetal nismo. Red looks awesome but is too noticable and flash so i went with the gunmetal.. looks great in the sunlight.
"terrible gas mileage"?? Think i'm av around 20mpg. Think that's bad.. my toy tacoma v6 double cab got around 16!
enjoy your new ride
