A CNC mill should also be capable of creating an usable driver bit, or in a pinch, drill out 1mm center of an ordinary + bit.
Plus, if you you are handy enough to be taking the screws out of your car but don't have a CNC mill, you probably know someone who does, who would love a little weekend project to turn you up a nice BMW screwdriver
