I have basically all the costs calculated, but there's one thing maybe the community can help me out with...
Does anyone know if BMW have a design patent for this M3/M4 side mirror? It looks like they have put design patent on several of the side mirror designs!! I can't seem to find patent information on the M3/M4 one though...
IF there's no design patent attached, then I'll be able to come up with a prototype in about 45 days...
