Ken from Woonsocket
I brought my 2010 Corolla in for an Oil Change and Inspection. I needed some small repairs to pass. Mike the service advisor was very helpful and knowledgable. The cost of the repairs was reasonable. Rte 146 has earned my business going forward
2021 GLC300 4matic
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.

Purchased a Tesla recently.
Purchased a Tesla recently. Sale was easy, staff was knowledgeable and accommodating. The cars at Authobahn are of superior quality and very clean.
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.

Carmart is a professionally managed business.
Carmart is a professionally managed business. The places I went to before could not find a financing method for me. However, when I went to Carmart, Mustafa patiently took care of me and made expert moves in financing transactions. Thanks to this, I was able to buy my car. I thank them very much.

Leased a 2019 Nissan Altima
About 2 weeks ago I went into Bertera Nissan in Auburn Ma. to lease a car. I ended up leasing a 2019 Nissan Altima. First off, I Love the car! It is a really sharp automobile, with a classy slick new design, a lot of technology, a great safety record, and a smooth ride! My experience was excellent. The salesman David Anglin, was polite, professional and very accommodating. Vinny the financial representative, was personable and efficient. Also, the sales manager (sorry, I can't recall the name), was both personable and accommodating as well. Although it took a bit of time to work out lease deal specific to my circumstances, they eventually they worked out a good lease deal for me! I highly recommend this dealership for anyone looking to buy and/or lease an new automobile! Sincerely, David Tucker

Felt welcomed the moment we walked through the door. Knowledgeable staff, great prices, spectacular inventory. We found the car we wanted. Frederick helped us with the car, he is everything you want in a salesman. Frederick listened to what we wanted in a car, worked with our price range, he wasn’t that typical car salesman you always hear about, he was great, truly caring. We will definitely return to Autobahn USA when we need another car.
