Great Boston BMW service!
Since the 90’s I have owned 5 used BMWs. Once you drive them you don’t change horses. I have been bringing them for service there since 2009. Great service and no need to wait for parts as in other garages. They are stocked. And they treat the earlier models (older) BMW customers as well as they treat someone who is either buying a brand new one or has a new one. They run the cars through the wash when finished and wipe down the interior and vacuum - and it is a very classy touch. The wifi is strong so you can get work done when you are waiting for a repair. It’s painless.

I absolutely love this compact SUV! Coming from a Subaru Outback, this is light years above and beyond for same year. A quiet cabin is my top want for buying a car. This cabin is quiet and relaxing inside. I’m tall and there is plenty of room. The seats are incredible! Can’t wait to take it on the roads in winter.

Most of my dealings were with Chan.
Most of my dealings were with Chan. He kept me updated throughout the process without putting any pressure on me to buy or not to buy. I finally did purchase a2020 Fiat 124 spider Abarth. The car is everything Chan said it was. Couldn’t be more pleased.

Michael has been super helpful and is with you every step
Michael has been super helpful and is with you every step of the way. Made buying a car the easiest process ever. Would recommend 👌.
Exceptional Comfort
I have had this vehicle for only one month so have not developed much experience with it. I did take it on a 1400 mile trip two days after purchase. It ran well, was very comfortable to drive, made for a very easy trip, was great on gas mileage, and it is very quiet inside the cabin. Seat comfort is exceptional and this, being our first experience with heated seats and steering wheel, was most enjoyable.

Great experience
Have had great experiences here.bought a 2009 Jeep Grand Cherokee 3 years ago that I’ve had no problems with. we just passed it down to my Daughter.A couple months ago we went and bought a 2014 Jeep Grand Cherokee. When we test drove it we mentioned that the rotors looked a little beat up when we went and picked up the jeep it had brand new Pads and rotors on all 4 tires. We only mentioned the front. They go above and beyond to make sure there customers are happy. Defiantly will be going back for a third vehicle next year when my other daughter gets her license
