I would also support you locating a reputable independent auto service shop that specializes in German cars. Make sure you locate one that specifically states they have M-B experience. They would be able to work on any aspect of the Crossfire regarding powertrain & rolling chassis. With regards to the Crossfire's Chrysler-designed stuff, your best source for DIY repairs is this Forum. And, as onehundred80 stated, this Forum might be your best source for any & all repairs of the Crossfire. We sort of have "been there; done that" experience. Even if you were planning on taking your car to a reputable repair shop, you could at least research your problem on this Forum, and most likely, find someone who has completed that repair as a DIY process. That way when you go to the shop, you'll have a good understanding of what your problem is and what it takes to get it repaired. Even a good & reputable German-make shop can take advantage of you if they see the opportunity.
