I just purchased a Black Premium on Stone. I have a small 1 car Garage I don't park in there storage. And its at an angle. Any cleaning tips ? I couldn't decide on what color. My last car G37 was Graphite Shadow on Graphite. So I wanted a change. That left it between Black & White. I got a great deal on the Black. The car was in stock. The White wasn't. The same exact car without the 19" Wheel package at another dealership was $38 More a month & An extra $500 Down. Thanks for any input.
