Bloody heck I have one of those fitted to mine - no idea they were that much - I'm used to the fabric ones which I like because at night you don't need to dip the interior mirror!!!That is the official name. Made specifically for R171.
It looks like this
minus the AMG decal ($12)
Every time someone asks about wind blockers for the R171, I have to go looking for pics and instructions, etc. So I made this thread.
2004/5..original price $810. Now on ebay about $450 or if a member sells theirs, maybe $300
Part number: A1718600174 B67812227
Install instructions attached
Yes, Lexan. According to your link: "I’ve never found a product that will restore damaged Lexan back to LIKE NEW." Ah well. Maybe I'll try to figure out a DIY.This is a good article... can you post some pics of yours? Mine is marked "Lexan", is yours?
