There is a really good Mercedes dealership near me that knows all about the Crossfire/Mercedes relationship and is more than happy to work on the car. They may not do warranty work but they will do anything you want if you pay them. They have all the tools and I don't think Mercedes is going out of business anytime soon.

I wouldn't worry and buy the car. Enjoy it! It is an amazing machine! I don't care what anyone says.... the car is amazing!
