The absolute greatest
My experience buying a used car with Dennis Morin was simply perfect. No pressure, he answered my questions and concerns. Financing was quick and easy. My overall experience was excellent. I definitely highly recommend colonial Cadillac and Dennis if you want the best!

As good as their word!
I always have an interesting car. I recently bought an AMG SLS Gullwing Coupe from MBOB. The sales associate, Mike, was exceptional. I did not have the car inspected, since MA has an auto warranty requirement. When I received the car, it did have a small oil leak. I have to say, I was concerned, since anything on an AMG car is expensive. However, after corresponding with Stephen (MBOB Service Director) and Tim (General Manager) they were good on their word and they coordinated with MB of Tucson for a valve cover gasket replacement. The car is fabulous, its condition is now perfect, MBOB's response was great, and I would not hesitate to buy a six figure car from them again!

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 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.
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.

Excellent experience.
I contacted them for a car listed on the Internet. It had been previously sold but they assisted me graciously and offered to find me a vehicle.
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.

Dakota was honestly the best sales associate I have ever
Dakota was honestly the best sales associate I have ever dealt with. She was professional, kind, straight to the point and fast. I was able to close my loan in 3 hours even with adjustments needing to be made on the paperwork because she made me a priority. Dakota was responsive to all of my silly questions and made sure my car was ready when I was available to pick it up. I would 100% recommend Dakota to anyone looking for a new or used vehicle because she will make it happen fast and smooth

Buying Made Easy
Buying a car from Mo was great. I do not like buying cars. I do not like the standard buying script. Thankfully, Mo talked me through the process. Showed me a coupe of vehicles and never pressured me to buy. With his assistance, I was able to make the buying decision that was best for me. In my experience, the prices were more than fair. The team was awesome and they continue to work with you after the sale closes. If you have researched your desired vehicle. Know the prices and what is available. Go see Mo. He probably has the car for you at a great price.

Amazing place to buy a car
Amazing experience. I'd recommend anyone looking for a car to try CarMax first... There's zero pressure, tons of beautiful vehicles, and just an all around great place. Will definitely be buying from here in the future. They're willing to work with you if you don't have the best credit, and most importantly, they're just honest and transparent. Two very important things when spending tens of thousands of dollars. Put it this way, it was great enough experience for me to come online and leave reviews all over!

New Tuscan
My lease was coming due and I shopped around at all different dealerships and ended up back at Nashua Hyundai. Not only did i get a great deal but great customer service as well. David Ritter went above and beyond to make sure I had the best experience ever! He was knowledgeable, professional and had a great personality, He made was could have been a stressful experience into a relaxed one. I will definitely return for my next car!

Great experience!!
I had a wonderful experience with carmax in Westborough. Very friendly staff, very clean. They don't harass you. Upon entering the building, I was greeted and directed to the vehicles I was interested. I ventured the lot on my own and able to check out the vehicle. All the details were located on the window or they have touch screens with the info of the cars on the lots. Chris C was my sales person, he was very quick to respond to questions I had after I left the lot and also gave me detailed information about the cars I was interested in purchasing without haggling me to buy the more expensive car. When I had a question for him he would always answer it and send the brochure or the car detail info so I had it. The day I made my decision I was driving off the lot in a preowned vehicke within a few hours. I was extremely happy with my experience and would recommend Carmax in Westborough for anyone searching for a preowned vehicle. And i had been to other dealerships for test rides.

Nice dealership, pleasant experience
My wife needs to retire her car. We are looking at three brands and this was our first stop. We spoke to Brockton and he made it a great experience. If she decides on the Mercedes we will be back.
