In Europe, I've driven cars with an aspheric driver's mirror. The outer edge is concave so the blind spot is almost eliminated. I'd like to buy one without going to Europe. I don't know if it's available in Canada. Anyone know if it can be ordered either through a Mercedes dealer in another country or if a company or dealer can order it here in the U.S.

Technically, aspheric mirrors may not be allowed in the U.S. even though it doesn't harm anyone.
