Just wanted to repeat the recommendation from others for the Art of Tint (www.theartoftint.com). Tom is very knowledgeable, and very experienced with MB's. Had miy E500 done last week (50%) all around. (yes, I know I could have gone darker). Very easy to deal with and considering the effort that is required to do a job like this right, the price was very reasonable -- less expensive than quoted to me by a local shop on Long Island.
