Mercedes-Benz of Palm Beach

Received a repair estimate (September '09) for over $5,000 for my S-class auto with under 30k miles. I took it to another mechanic shop that specializes in Mercedes/Rolls/Jaguar. They completed the same repairs - part for part - and the total charge came to $1490. Mercedes Benz Palm Beach in West Palm was OVER THREE HUNDRED PERCENT more expensive than this other repair shop that has been in the luxury foreign car repair business for over twenty years. To add insult to injury, when I told MB Palm Beach that I wanted to get a second estimate since theirs was so high, they tried to charge me almost $300 for a "diagnostic fee." Since that was never mentioned up front, I politely declined their offer to rip me off and had the car successfully repaired by a professional outfit for two-thirds less than their estimate. I would be suspicious of the Mercedes Benz Palm Beach service department.
