Awesome - Laid Back - No Pressure - Knowledgeable
I would purchase from them again in a minute. Very good vibe. They all obviously have a great culture there. It rubs off on the customers. Good value for the money.
2021 GLC300 4matic
I absolutely love this compact SUV! Coming from a Subaru Outback, this is light years above and beyond for same year. A quiet cabin is my top want for buying a car. This cabin is quiet and relaxing inside. I’m tall and there is plenty of room. The seats are incredible! Can’t wait to take it on the roads in winter.

Went well done within an hour.
Went well done within an hour. Also received a multi point inspection. The service consultant top-notch I bought the vehicle in another Honda dealer but been doing service here instead. Much better Effort at Gwinnett Pl., Honda.
Exceptional Comfort
I have had this vehicle for only one month so have not developed much experience with it. I did take it on a 1400 mile trip two days after purchase. It ran well, was very comfortable to drive, made for a very easy trip, was great on gas mileage, and it is very quiet inside the cabin. Seat comfort is exceptional and this, being our first experience with heated seats and steering wheel, was most enjoyable.

My experience was amazing, however, I didn?
My experience was amazing, however, I didn?t expect an enormous increase in monthly payments due to my fixed income. My sales representative was the bomb! He is the best! He was busy, busy, busy selling cars left and right. His desk is lined with awards to prove his impeccable abilities and skills. He is truly a professional salesman. Many of his customers told us he was a very nice man. I always return to him for my cars.
Great vehicle
This car has everything technology offers in it plus more. The feel of this vehicle is extremely smooth snd quiet. One of the best purchases of ever made. I’m extremely pleased and love it

Great Customer Service and Assistance
The salesman (Jerrel) was great to work with because he helped me while he was there Orr if he was off that day. He got me a car from another store then found out there were problems and found me a car around the same price range that was newer and less miles. Thanks for everything!

After entering my 2020 E450, I got a display message that said "12V Battery. See Operator's Manual". Sent a quick note to Mitch Griffin thinking after 5 years a new battery was probably needed. He responded and after contacting RBM, Jordin Mendez was dispatched to my house. In about 20 minutes, the battery was replaced. Great job by Mitch, Jordin and my phone contact at RBM. Much appreciated!

I was in the market for a new car for over a year now.
I was in the market for a new car for over a year now. It is nerve wrecking and overwhelming. Decide to buy a new or used. I researched, test drive, and contacted over 20 dealers for information. Until I finally found the perfect car for me at the perfect price, while on the CarMax website in Norcross, GA. A 2023 Nissan Pathfinder SV 4WD with 16,500 miles. Practically brand new and at least under $2,000 and the lowest miles from similar vehicles in my area. One great thing about CarMax is that I was able to scheduled the test drive 7 days in advance. They reserved the car for me, no worries about being sold before my test drive. Another great thing about CarMax is the price advertised is the price you pay. Other than tax, title and registration, no other “bogus” fees are added to the price. I only wish they offered special incentives/discounts like military, first responders, student, etc. But, I am extremely happy with my purchase!!! Shout out to salesman Young!!! He is the first person I spoke to; he got the car for my test drive, and in less than 1-2hrs I was on my way home with a new car!!! In other words, DO YOUR RESEARCH!!!

I had an amazing experience at Gwinnett BMW! Will Pickney was an outstanding salesperson—professional, knowledgeable, and truly dedicated to helping me find the perfect car. He made the entire process smooth and stress-free, answering all my questions and ensuring I was comfortable every step of the way. On top of that, I got a fantastic deal on an incredible car! If you’re in the market for a BMW, I highly recommend Gwinnett BMW and asking for Will Pickney. You won’t be disappointed!
