During the 15 years I had my 98 C5, I broke 3x passenger mirrors...or rather I broke 2 and my wife broke one. I found the first 2 from doing a North American wide wreckers search...the last one I found on eBay. Prices vary considerably...the eBay one at the time was half the price of what wreckers wanted. I haven't hit my C7 one yet backing out of the garage...knock on wood! Good luck.
