If you are looking for a lightweight, effective windshield sunshade, try HeatShield from Canvas Works in Sunnyvale, CA. Their model number for the W211 is HS#892 for Mercedes E-Class E320/E500 2003. Price is $29.95. It is lightwieght and rolls up for easy storage. I have used one for each of my cars for several years. It really works to minimize heat intrusion from sun, protecting the dash and front seats, too.

 

wow that is cheap, especially in cali, sun is leathers worst enemy, thanks

 

I purchased the MB sunshade for the new E. Haven't used it yet, since my car's been in service since Oct 31st. The motor mounts came in yesterday and got installed today. The new keys also came in, but apparently did not fix the keyless entry problem. (I told them it was something else.) They are supposed to try and resolve it in the morning and call by Noon. Don't think I'll hold my breath. BTW - the MB sunshade was $70+ through parts.
