depends on the Merc shop.

Tried every one in Southern IN, back in Dec, none will even look at the Xfire. Wanted a simple check of the work my Chrysler dealer had done to the car. A couple individual mechanics at the shops offered to do whatever I wanted on the side, though.

Funny note: Everyone of them knew exactly what a crossfire was, and many of the mechanics I spoke to would have been really happy to stick there noses under the hood and see what Chrysler did to their babies. But the shops themselves were unwilling to touch the Chrysler badging.
