Nice lookin' car!! Gotta love MB"s real leather seats, eh? My seats look very similar (except for being "pink"-omino), in spite of the rest of the interior looking good.
I don't know about the headlight wiper conversion; in fact, except for people who've put Euro lights on, I don't know of anyone who's done it...
Again, congrats on the purchase!! Now you gotta change your sig...
