You're quite right about silver not showing the dirt so much. With granite I have condemed myself to a lifetime of washing the car
But when its all nice and shiny - - - Its soooooo nice :D :D :D
Its looks like it has flecks of gold through it and just looks so rich and smooth and !!!!!!!!
Perhaps it does have gold in it, and thats why they could only afford to put on such a thin coat?!! :P
I think if you're going to have a new car, have a different colour. It may make it feel newer in some strange way, rather than a straight swap, or something. Err - I'm getting myself confused now so should stop.
