Winchester Auto Service

Very thorough work and most organized service department I have seen. Pictures to go along with their recommendations and upfront/honest. Wish I would have used them from the beginning for my BMW.

Great and speedy service ! Felt comfortable having my car here and they helped accommodate my schedule

Excellent and trusted service as always from Andy and Dave!

As always Andy and his team provide first class service at the highest levels of competence. They provide thoughtful advice on work that may be needed. The work is done promptly

Excellent service

Outstanding service from an otherwise unpretentious business! My BMW unfortunately developed serious suspension problems during a short visit to Boston. They were not only able to squeeze me into their busy schedule to look at my car, but they even had parts delivered the same day and got me on my way for my 4 hour trip back home! Andy appeared extremely knowledgeable, meticulous and informative. This place is so impressive that am thinking it is worth driving 4 hours every time I need 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.
