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

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!
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.

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.
