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.
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.

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

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

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.

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.

Genuine interest in pleasing the customer
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!
Great Vehicle
I absolutely love the feel and performance of this suv. The electronics are state of the art. Excellent road performance in rain, snow or wind. My only complaint is the running board- it needs to be at least 1 inch wider. Actually dangerous in snow and ice.
