with a white car your not going to get the breathtaking results that other colors can achieve. Yes, it will still look great, but don't expect too much. The key to making white look good is to have a very sharp contrast between the perfectly clean paint and the darker colors present on the car. Dark tint on the windows, jet black trim, perfectly clean wheel wells, and freshly dressed black tires will give great contrast and really augment your work on the paint.
White does show itself nicely in the twilight hours though.
