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.

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.

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.
GLC43AMG
I have the GLC43 AMG and it's awsome! It has plenty of guts and is extremely comfortable. I would highly recommend this vehicle to anyone.

I did as much research as I could on the 2026 EQUINOX.
I did as much research as I could on the 2026 EQUINOX. I made some online enquires and got phone calls from many different Chevy dealers. Then it took days before they would get back to me and some not at all. I got a call from Tony Dillberg. I told him I was waiting on some information from other dealers. He told me he was willing to be aggressive to earn my business. I explained that my time was limited and can we do the negotiating over the phone. He asked if I had a trade and told him yes, but couldn't make it over for a few days. He said no problem we can send someone to your home and take care of that. And he did. We came to terms on a deal. After that was settled I asked how soon I can pick up my new vehicle. I explained that it was a surprise for my wife and was picking her up from the hospital the next day and wanted the WOW factor when doing so. This was at 2:00 PM in the after noon. He told me I can pick it up by 7:00 PM that evening. SOLD. When I arrived he introduced me to Paul Deleon and he took it from there. Paul was knowledgeable with all the questions that I had and a pleasure to work with, he went over all of the paper work and formalities and then got me familiar my new Equinox. Picking up my wife the next day and the look on her face seeing her new shiny new red Equinox was a surprise of a life time for her. I got the WOW factor, missioned accomplished. Thank you to everyone involved at MacMulkin.
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.

This was the best experience with getting a first car, just the first step into the dealership is like walking into grandmas house, a warming feeling relatable music and the most upbeat personality’s, and the sales person that helped me with getting my first car which is a bmw 5 series 535i xdrive, his name is pedro and he was the most helpful and funny person to interact with, he kept me from getting nervous or upset he even talks about things in life from how he started sales to how to take care of your face routine, this is the best place to go to acquire your first car!

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

Wesley was very professional didn’t question my offer brought it right to sales manager. Negotiation was smooth in the end I paid what I thought was a fair price and got a powertrain warranty thrown in. They delivered car promptly inspected and filled gas tank. Very positive experience no pressure. Thank you guys at Autobahn Westborough.
