Someone I know was telling me that the M5s have alluminium panels, doors boot, bonnet, I was'nt sure of this as only recently I had some small dings removed from boot and bonnet, the repairer used a whole range of levers and various shaped lengths of steel so no bog sanding or paint and also used mirrors which were mounted on the panel by a magnet! I did not think magnets stuck to alloy ? Can I be enlightened please. cheers Steve
