Ironically, while searching for auto-dimming mirrors for my ML on eBay, I bid on (and won) a set of 96 W210 sun visors. I am particularly interested in the Homelink controls on the driver's side visor, and although grey (my W124 interior is Palomino), I still plan on retrofitting the Homelink unit to the W124.
If it's successful, I can truly say that all of my MBs have Homelink!
