Midway Automotive
They were excellent. They got me right to the car I was looking for and They did not attempt to add any illegitimate fees to increase the price. They got the car ready for me so I could pick it up the next day ready to go. The experience of getting a car from this place went as well as it could have gone. I highly recommend them. The person who helped me was Frank Santino and he was easy to work with.

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.

I recently had the pleasure of working with Adriano Carlo
I recently had the pleasure of working with Adriano Carlo at the Lynnfield Nissan location, and I can confidently say it was one of the best car-buying experiences I've ever had. From the moment I walked into the dealership, Adriano made me feel welcomed and valued. His professionalism, knowledge, and genuine enthusiasm for helping customers were evident throughout the entire process. Adriano took the time to thoroughly understand my needs and preferences, guiding me to the perfect vehicle that met all my criteria. He patiently answered all my questions, provided detailed explanations, and never once made me feel rushed or pressured. His expertise in the features and benefits of each car was impressive, and he ensured I was fully informed to make the best decision. What truly stood out was Adriano's commitment to customer satisfaction. He went above and beyond to secure a fantastic deal and made the entire financing process seamless and stress-free. His attention to detail and dedication to ensuring every aspect of the purchase was handled flawlessly was truly remarkable. Adriano Carlo is a shining example of exceptional customer service. If you're in the market for a new vehicle, I highly recommend visiting the Lynnfield Nissan location and asking for Adriano. His professionalism, knowledge, and sincere dedication to his customers make him an invaluable asset to the dealership. Thank you, Adriano, for making my car-buying experience truly outstanding! -Lisamarie M.
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.
Great vehicle

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.

I usually get SUVs or Trucks from American Brands. I wanted to get my self a really nice seadan. My buddy recommended me to go to Mercedes-Benz of Burlington before I go to any other luxury dealership. His recommendation was spot-on. Dealership is beautiful with a waterfall fountain plus a nice cafe. The staff is extremely accommodating. I met Collin Stankard valet who took me to TJ a sales associate. TJ was patient and helped me find the right car for my needs. Chris Caputo GSM took the time and found the proper numbers to make me happy because I like to haggle. Then I sat down with Steve Baker a finance manager me made the paperwork easy peasy. Elaine PC had an awesome delivery for me. I learned the ins and outs of the car. Tim Martino the GM was out on vacation but made sure that everything was done properly and I was treated like a VIP. My father was in the car industry. I know the games and gimmicks the people like to run. I'm extremely happy that I only had to go to one place and had a great experience. I'm now part of the mbob family.
