New and used 2025 Mercedes-Benz C-Class C 300 4MATIC for sale near Topsfield, MA

I recently bought a Certified Pre-Owned Mercedes-Benz E 450 at Mercedes-Benz of Portsmouth. It was a very nice experience working with Cynthia Acorace, my sales associate. When I picked up the car, they let me know that it was missing the key to the locking lug nuts, but they were ordering a new kit and would let me know when it was ready. Cynthia sent word to me that the kit came in and I could come at my convenience and a tech would change the locking lug nuts and give me the new key. I went in yesterday, and Cynthia took me to the service area where Cory Counsil was supervising the department. When Cynthia explained why we were there, Cory sighed and explained that there was a problem with the service software, and they had allowed all the techs to go home early. Cynthia escorted me to the customer lounge where I had a complimentary cup of fresh brewed coffee, and began to browse through the gift area where they sell Mercedes logo shirts, key chains, and coffee mugs. After a moment, I looked out the window and saw that Cory himself was changing my locking lug nuts. Within moments, Cory had gone the extra mile, and, even though there were no techs working, he took care of things personally and came to find me, telling me it was ready. Cynthia, caught up with me before I left and was concerned to see if I had any questions about the car, now that I had been driving for the first week after buying it. I did have some questions about the automated parking features and how to use the shift paddles. At that point, another sales associate, Ben Lamont, came over and gave me an encyclopedic dissertation on how the parking assist feature worked, and then he showed me how I could easily get in and out of manual mode with the shift paddles. Ben's enthusiasm for Mercedes automobiles was evident, and he made me really feel good about my purchase. From when I was first visiting the dealer, as an off the street shopper, browsing the inventory of cars, through the sales experience, and now as a customer needing help, I have visited this dealership a half dozen times over a 3 to 4 week period. During all those visits, everyone has treated me like a VIP. I was never made to wait, and any concerns I had were taken seriously and addressed immediately. I would recommend this dealer to anyone in the market for an upscale car, and tell you to ask for Cynthia or Ben.

If you are looking for excellent customer service and customer care, I would highly recommend Mercedes-Benz of Boston. Ryan Ramsingh is very dedicated and knowledgeable. My car needed some things to be removed and replaced. Ryan explained everything in detail with a positive attitude and helped me understand and come to a decision on what was best for my car. Mercedes service has exceeded my expectations.

Excellent and on time service, Mike Robinson the service rep was very nice (as always), and a fine loaner vehicle

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.

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.

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.

Peter Derby is worth his weight in gold. I live in France and he was brilliant, he sent me a picture of the parts to confirm the correct ones, arranged delivery to Portsmouth confirmed their arrival before charging me anything. Once paid ,confirmed that they were sent job done! All done in a calm professional maner. Perfect 11/10

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.

Mercedes-Benz was extremely helpful when it came to helping me with the purchase of my new C300. The facility was immaculate and team very accommodating.

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!

As first-time customers, our experience at Mercedes-Benz of Portsmouth was exceptional right from the first phone call. I told my initial contact (Bethany) what pre-owned vehicles I was interested in, and a time I was planning to visit. When I arrived both vehicles were parked next to the show room waiting. We were greeted by Nick in Sales, given a brief overview of the 2 vehicles and then given the keys to take them for a test drive. For all 3 of our test drive visits the vehicles were waiting, normally running, and always nice and clean. We were never rushed, and there was never any pressure to choose, or make an offer. All questions were answered quickly and thoroughly and all information about the vehicles and vehicle histories was transparent. We were never steered towards any particular choice. Negotiations were quick and straightforward. We picked up the vehicle on a very cold day. It was sitting in the showroom perfectly detailed and all warm. Everything promised was delivered - even the front Weathertek mats! Finalizing the deal was a breeze (thank you Paul) - again very straightforward and transparent. These folks like what they do and it does seem they are allowed to do whatever they can to accommodate their customers. Very nice experience!

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

Bethany, Tuck & Paul created a great, honest and personal experience at Mercedes-Benz of Portsmouth and my purchase/trade was top-rate in all respects. Your dealership had a very unique used car in stock. I came from out of state and each of you exceeded my expectations on the service, attention, quality and condition of the car as well as your preparation and welcoming treatment of me on site ! Thanks again ! Jack L. -- Virginia
