Picked these up online from a company that does BMW products and now custom makes blindspot mirrors for Tesla models, too. The clarity is really incredible, does not have the distortion of usual convex mirrors and fits the shape well of the M3 mirror. I'm just not big on looking at the screen for the blindspots. Incase of emergency, I like a quick glance in the mirrors with a lot f visibility and this fits the bill. The company is down in the San Diego area, so they came quick!
