I was dissatisfied with the quality of service I received at a local dealership, so I started looking for alternatives. I have been more than satisfied with the quality of service and professionalism offered by Dave and the other members of the Bavarian Performance Group team. The shop is well-equipped for standard maintenance as well as advanced telematics retrofits from BimmerTech and performance upgrades from Dinan. The shop does extremely thorough work, finding (and meticulously documenting) issues that other dealers should have called out. If you're looking for a good BMW mechanic in the greater Boston area, look no further! I won't be taking my cars anywhere else.
