Mike Robinson is a great advisor. Helped me address an issue with the car very quickly and efficiently.

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..

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.

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

Cynthia, Ben, and Cory were great!
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.
