Another buyer beat me to the car but I was very impressed by the professionalism, information and great communication provided by this dealership!
My Sixth Mercedes Benz-Fantastic Cars
The GLS has the luxury of a sedan and the versatility of an SUV. This is the fourth GL series that I have had and would not consider another vehicle.

Ms. Mabie was great! She was very responsive to my questions and was quick to get back to me with my requests. Too bad it didn’t work out this time around, but will be keeping her in mind with future car purchases!

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..

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!
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.

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 SUV
My 2 honest cents. Just bought the 2024 GLS 450 and it has a huge presence on road and it looks stunning! I went with the AMG exterior package and it looks way better than the base model. Ride quality is good, very smooth ride on freeways but you do feel small bumps on occasional city roads. The engine is good but I wish it had a bit more power, feels little laggy at low speeds but when you floor it it moves fast and steering is very responsive. On the other hand, cabin very silent tho and you barely get to hear road noise (without acoustic package). The Mileage is incredible on this, wasn't expecting to write about it but the GLS gives better mileage than my GLC. Interiors are amazing and is something no other manufacturer in this segment can match (especially at night with ambient lights), seats are super comfy and the infotainment screens are also crisp. Overall, love this SUV and i'm gonna keep it for a while.

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.

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.

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.

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.

Gold star treatment
Went to 3 other dealers before being reccomend to matt Harris and knew instantly it was our last stop. We has been treated like xxxx at the other dealers. 1 lied to us and another told us he would not replace bald tires on a 2 year old luxury vehicle. The second we met Matt we knew we were In great hands. My fiance got the Mercedes she wanted at a fair price and the vehicle recieved everything it needed in the shop before we looked at it. The finance guy treated us like human being and never once felt like I was being had. Oh I forgot to mention that I sold cars for the last 17 years so I recognized great people right away. We will always be loyal to Matt and appreciate everything he did for us
