I bought my car at this dealership a number of years ago.
I bought my car at this dealership a number of years ago..And coincidentally, I had a flat tire happen to me right around the corner from them. They replaced the two front tires (worn enough to merit requiring when changing one we needed to change the other). The process was quick. And while they needed to receive the right tires overnight they also cleaned the car quite thoroughly. Everyone was very nice and helpful.

I’ve had many Mercedes-Benz models over the years, including AMG’s and the GLS 450 a wheel drive with 23 inch wheels makes this car track like a race car. Out of all the Mercedes-Benz models this is the best one you’ve ever had. The second row seats reclining just like the front row seats privacy shades and the third row comes in handy when needed plenty of cargo space for all those trips to the airport to pick up family and friends. It gets great gas mileage then other SUVs and it doesn’t look like a box like it’s competition. I had the dealer put the Mercedes-Benz standup medallion on the hood even though it has a huge Mercedes-Benz insignia on the front. I just like to see the stand up Star medallion from the driver seat guide me down the road..

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!
Very happy with my purchase from RBM Alpharetta.
Very happy with my purchase from RBM Alpharetta. The car has a very comfortable interior with all the features available. Handles well in town and on long drives. Good acceleration for such a big vehicle. Love the contemporary exterior.

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.

Unicorn. Great car, great price, great service!
Found 2014 Audi A4 Quattro manual transmission on Saugus Auto Mall website and called after hours to set up a test drive for the next day. Car was in great condition and was really fun to drive. Though the car's price was very competitive for the market (we shopped around for a few weeks) it was just slightly outside of our price range and they were able to meet us in the middle. We test drove the car for a second time the next day. Both times there was no hassling or pressure from Ali or the Saugus team. We decided to buy the car cash and everything went so smoothly. When we got home we realized it was one of those unicorn car buying experiences. The DMV is super slow right now during the pandemic so we had to wait for a full week for our paper plates and registration to come through. The car was fully detailed and everything was in order when we came to pick it up. Also, we had asked for one of the tires to be replaced because it was damaged and they ended up replacing ALL four tires! Great experience buying a used Audi! Thank you to Ali, Mike, Jason and the whole team.
I bought this vehicle is a retirement car.
I bought this vehicle is a retirement car. He moves great is responsive and very smooth. I wanted a retirement car for my retirement. I am 60 years old and I want that something that represent my current status with luxury interiors, beautiful blue color, and 20 inch wheels it is awesome looking. I can reach 70 in the blink of an eye any moves like it's going at 30 or 40 miles an hour. He has an awesome radio system. although it is not all digital, the radios are for listening. I have an excellent sound, System. Great interiors, great materials, great lighting if you're planning to buy a GLS the 450 is definitely one of your best choices.

11/28/2025 I called Schneider at around 7:52 a.m. He then gave me the towing company’s number to arrange for the car to be towed at 8:39 a.m. At 9:29 a.m., Schneider called me to inform me that the tow truck had arrived at the dealership and that they were going to find out what happened with the power steering. He called me later and told me that the car was ready. Furthermore, he went the extra mile to check whether I was covered by my extended warranty. I had a great experience with Schneider. Kami P.

Honest, customer service.
I am from out of state, and made an inquiry online. I received a prompt reply and followup from a salesperson. Although I did not make a purchase at this time, I will definitely give them another try when circumstances change.

If I could give 10 stars I would!
If I could give 10 stars I would!!! I recently had the pleasure of purchasing a used Porsche, and the entire experience has exceeded every expectation I had. From the moment I began inquiring about the car, the dealership was responsive, professional, and incredibly thorough. Despite the car being located in Boston, I was initially hesitant about the logistics of having it delivered all the way to Indiana. But the dealership went above and beyond to make the entire process seamless. Timothy Klingenberger specifically was a DREAM to work with and someone I now call a true friend. He had my best interest in mind from start to finish. I can’t usually say that about any car dealership. Tim provided detailed photos and videos of the car, ensuring I could make an informed decision from a distance. The condition of the Porsche was exactly as described, and when it arrived, it was even better than expected—immaculate, with every feature working flawlessly. It was clear that the car had been meticulously cared for, and the quality of the vehicle far surpassed anything I’ve ever experienced in a used car. Not to mention and without my asking Tim included a second key fob at no additional ask or charge to ensure I had two as it would have come with when purchased new. The delivery process itself was smooth and efficient. The car arrived on time, in pristine condition, and with a full inspection report included. It was evident that the team cared about customer satisfaction and that they were willing to put in the extra effort to ensure I was thrilled with my purchase. What really stood out to me was the attention to detail and customer care Tim gave me from start to finish. I’ve owned several high-end cars, but this was by far the most seamless and satisfying purchase I’ve ever made and I can be picky. If you’re considering buying a car, I would highly recommend this dealership. They truly went the extra mile, and I couldn’t be happier with my decision.

Stephen Leung at Mercedes-Benz of Boston is the finest sales consultant? I have had the privilege of working with either at this dealership or any dealership in past years. He is professional, extremely knowledgeable, articulate, and a pleasure to deal with it gives you the pluses and minuses and is completely honest. I highly recommend him.

Very easy and enjoyable buying experience. Seamless leasing / Finance experience. Beautiful facilities and car lineup. Would highly recommend for anyone looking to purchase a luxury car.
3 month review
I purchased the vehicle off of a lease in March with 60K miles. Overall I am pleased with the purchase. For the size the SUV is very nimble. The surround camera is a must. On a 350 mile round trip my 5'6" daughter-in-law had no issues sitting in the third row. I put the car seat for my grandson in the 2nd row drivers side because lifting the 2nd row back after 3rd row access is cumbersome and heavy on the drivers since you have to lift the middle seat as well. MB you have to make the 2nd row power back to upright position. Adaptive cruise control is outstanding but keep in mind you have to get the Driver Assistance package to get it. Harmon/Kardon surround sound is very nice. My big complaint is sometimes at speeds above 65 MPH there is front vibration. Does not happen all the time, sometimes I can cruise at 80 MPH and feels like I am sitting in my living room. I think it may have something to do with the Pirellis, I plan to switch very soon to Michelins. A very classy, roomy and comfortable SUV

Great dealer
I just got my second car from Avon auto broker they have the best selection and their staff is very knowledgeable and the owner Dana was very helpful. I highly recommend this dealership.
Almost perfect for luxury family truckster
Owned this suv for 15 months purchased certified preowned with 33k miles and about half the price of new. The truck has only two issues to note but otherwise rides, drives and in all other respects is far and away the best automobile I’ve owned - which saying a lot for an old guy. The standard tires are nearly useless in snow and ice and we hope an aftermarket replacement will address the issue later this fall. The more annoying downfall is that although the ride is otherwise amazing, the truck handles sharp bumps very poorly - almost the feeling of a car with workout struts. I have had the struts replaced under extended warranty but the improvement was marginal. For most drivers the suspension issue wouldn’t likely be as much an annoyance but for my fellow ocders, be warned. I would buy the truck again, however.
