Winchester Auto Service

Everything thing went as planned and new report of inspection (with pictures) was great.

Fast and friendly! I will definitely come back for any service my 328ix may need. (Massage chair in the waiting room was a nice touch.)

I’ve only personally interacted with Andy and Dave but they are stand up human beings that are honest and trustworthy. Plus, they do incredible work. From routine maintenance, Dinan work, and even tech. I’ve had all three types of work completed there and couldn’t be happier.

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.

Great service, as always.

Always professional and friendly. Repairs done quickly and communication is great.

Top notch service.

The guys here are fantastic, extremely knowledgeable and fair. The prices are better than the dealership, and I trust this shop much more than a dealership without question. Oh, and they use liqui moly for oil changes! If you own a bmw, there is no better shop.

Good and fast. The tech is no-nonsense and knows his stuff.

Timely work at a fair price!
