This product was listed for application to an E-class Benz. I took a chance and bought it for a W140 S-Class. It worked out beautifully, the only difference being that the S-class OEM mirror contains an additional motor for folding the mirror in against the body electrically - a function I happily do away with, in exchange for such a good value. This was a lucky find!
Sure saved a boatload of money, the retainers for the cover need to be back filled with wood to keep from coming off. Reused original black covers, don't latch securely without mods. Mirrors no longer vibrate and hang down.
