I just got my European mirror for 2003 E320 wagon. Old driver's side mirror was leaking. It's self dimming and heated. Expensive options that I don't need, especially with dealer MSRP for mirror at $700; that's just for the glass and backing plate that snaps in the housing. The German mirror does have the heated feature.
I have a contact in Belgium and he got me the mirror fitted to the car as sold in Germany and probably everywhere else except the USA. The price of the mirror was 62 Euros plus shipping. Photo is below.
The mirror is great. You no longer have a blind spot. The part of the mirror to the left of the dashed lines is different than the rest of the mirror. I think it's aspherical. You only notice the part to the left of the dashed line is different when a car is in your blind spot because now you can see it.
To bad USA dealers will not sell it. Part number is A2108100721
No, Mercedes Benz will not all them to be imported for sale thru dealers. However, aftermarket versions are available. Don't know of quality though. Check ebay for guy that sells aftermarket mirrors.
