Thanks Joe.
Shvegel, I don't mean to insult the MB engineers, after all we are 50 years farther down the road now, but as I used to say in the auto industry, "if I wanted something that didn't work, I could have got it much cheaper." That's a bad joke, but at the same time, I don't think it is fair that Mercedes should be judged on aftermarket parts installed by dealers. I would like to be a purist, but I won't be a masochist. My home-designed AC system may not work because I haven't tried it yet, but I installed a Sanden compressor and a single pass condenser.
But who am I to judge anybody. The previous car I restored was "pure", beautiful and except for the power train, a piece of junk. It wasn't a Mercedes.
