I can highly recommend Diamond Sunoco in Pikesville. Phil Diamond and his mechanics are honest, and know what they're doing on Mercedes. I just had a full front end re-do on my '75 450SL at a fraction of the dealer or specialty shop. I send 2 - 5 of my customers to him a month - deal is that if you're not happy you let me know and I don't send anyone else there and warn off the others - this keeps em on their toes! Tell him Dave from StudioDNA sent you.
