Apologies if there is already a thread on this ......but here goes: I'm about to put my private number on my M3. As those of you who have had your M3s handed over will know, the number plates supplied by Tesla are thin metal ones which clip (rear) or slide (front) into a plastic holder on the car. The rear one in particular has to be a very exact fit in the holder - the clips that hold it are very small and there is very little room for variations in plate size. I've asked Tesla who they buy them from (so that I can get some of identical size), but no reply as yet. However, when looking closely you find that the holder that the number plates clip into is held by two screws onto anther plate behind which is in turn fixed to the bodywork. The 'back' plate is perfect for fitting a standard UK size plate to using the screws that, as delivered, hold the outer holder onto the back plate plate. So, why bother with the outer holder? It appears unnecessary, and when you look at it is a truely cheap and nasty bit of c**p. The advantage of doing away with the holder and fixing the new plates direct to the car backplate is that the exact size and thickness of the number plates is irrelavant (subject to a bit of care over the screw lengths), so you can get them from any supplier. Any thoughts??
