I'm lovin that thanks!!!
after a few conversations and a few drawings, I've got loads more ideas now, so pick from this list:

1. Black roof, silver middle, gunmetal bottom

2. black roof, gunmetal middle and silver bottom

3. Dark blue bottom and off-white top

4. Olive green bottom and off white top

5. sky blue and white in any combination

as for wheels, I was thinking about those spokey mondeo wheels (16 inch , 10 spoke i think) that came in normal or chrome finish
