Thanks to all for the replies. I appreciate the advice.
A couple of things... first of all I am well aware of the Mercedes pedigree of the SRT 6, it's the primary reason I was attracted to it. The cost of an oil change for this car is of little concern to me, it's the thought of a major issue cropping up with the Supercharger that scares me. That along with the horror stories with service at Chrysler dealerships.
cgocifer, I think you have some very valid points about Chrysler scaling back support for the Crossfire. I can't imagine they are spending much on training new Crossfire techs capable of dealing with the 3 year old SRT 6.
I still love the looks and performance capabilities of the SRT 6, and the price is a major inducement too. But this isn't going to be a weekend cruiser for me, so I've got to know I can depend on it.
I've got a dilemma huh?
