Boy, that's a tough one Ed. Especially if you're looking for wood grain finish. Seems like I remember Poineer units a few years ago could have a carbon-fiber or wood faceplate, but I haven't seen any since
I'm looking for a new head unit myself, and a good one that blends harmoniously with the understated interior of my W124 (I hate the techno light-show that permeates the current selections). Nakamichi seems to make the best in both performance
and looks from what I've found. See
www.nakamichi.com. Also, I've seen their decks on ebay for considerably cheaper than full retail price.
I've seen Denon units too, that looked very nice for the interiors of MB's (but again, no wood trim), but I don't think they make car audio products anymore.
This is assuming of course, you would put something Japanese in your car!:p And you have a beautiful model by the way!
