It'd be difficult for him to claim (to the dealership) that he's a "loyal MB customer". These guys make their money off of service, not car sales. They absa-freekin-lootely need a critical mass of people to bring their cars in for $200 oil changes regularly in order to stay in business. They don't make enough off of just selling cars.

Sorry but I think the dealership was just protecting his own interests by refusing to reward someone who had a history of undercutting him for service. He's within his rights to not be a nice guy about it.

I'd take it up with MBUSA - they ARE in the business of selling cars (more so than the dealerships) and their acknowledgement of this problem via the TSB and subsequent refusal to stand behind the design limitations of their product is sleazy, IMHO. Seems very out of character for MB who in my experiences do stand behind their products... Maybe a consequence of things having gotten a lo slower the last couple of years (?) Regardless I'd focus my efforts there, not on the dealership. That's barking up the wrong tree IMHO.
