Just been ogling a Mclaren Merc 722S SLR roadster in their equivalent of Sterling grey. It had a very dark red, almost metallic sheen roof on and I can only say how awesome it looked. Shows it to be a good choice if it's ok on a £300k car.
'Stuck' in South Spain and no chance of getting camera pics off chip to pc so no pics to post, but will do so in the future.
