Me and you are in two different boats buddy. Although I have no answer to your original question, I can tell you I have owned Mercedes Benzes all my life. This past Novemeber I treated myself to a 2001 Corvette Z06 with 1100 miles ( I still have a '92 400E and a '00 ML320.) My MBs are daily drivers and the Z is my weekend warrior. This car has made my an avid Vette fan, and wouldn't trade it for the world. Anyway...good luck with the MB, you'll love it. This, just like the 3 or 4 Vette forums, is an extremely helpful tool in maintaining your MB and getting 200% of your questions answered. Enjoy!!!
