The service people at Royal Chrysler referred me to a local independent shop that 'specializes' in servicing the engines of 'German' cars (AutoCamp). I would highly recommend any owner of these types to use him.
My check engine light turned out to be a bad O2 sensor unit - a $725 part. One look under the hood and he declared "this is a Mercedes engine - it's bullet-proof".
I understand that servicing a Mercedes would be more than a domestic. To anyone thinking of upgrading to a Mercedes - these cars are much cheaper to buy and it appears you get the same/similar product.
Review about: 2004 Chrysler Crossfire Car.
Reason of review: They won't service what they sell.
Preferred solution: Nothing from Chrysler - this was a learning experience - how they stand by their products..
