my service representative was very professional and
my service representative was very professional and courteous. i have been using this location for 4 years snd the service and experience is always very good. my only complaint is the fact that they charge a 3% of total cost if you use a credit card.
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.

I had a fantastic experience purchasing my car here.
I had a fantastic experience purchasing my car here. I had been to several other dealerships, and this place was wonderful. Jacob was such a patient, knowledgeable, and sharp sales person to work with. Thorough and personable in the conversation and when answering questions. Han was so helpful and provided a great level of explanation in the finance piece of it. I am so happy I went here.

I had a very positive car buying experience working with CJ. From start to finish, he was attentive, objective, communicative, and transparent. He took the time to answer all my questions, kept me informed throughout the process, and made sure everything went smoothly. I really appreciated his professionalism—no pressure, just helpful guidance. Highly recommend working with CJ if you're in the market for a new vehicle!
Best SUV we've ever owned.
Exceptional vehicle in the SUV class. We drove the BMW X7, Audi Q7, Volvo XC90 and this GLS 450 just kept blowing them out of the water. The ride is amazing and we feel the comfort level and size is the best

My shopping experience @CarMax Roswell, Ga
My overall experience with this dealership and sales associates were very pleasant and sufficient. I was able to take my time in selecting my vehicle and was given accurate pricing info as I had already did my research for the car I was interested in. I wasn't pushed into a car I didn't want or desire after I decline to purchase the original car I went to the dealership to test drive. The associate took the time to look through the online lists of cars within a 150 miles of his dealership and after locating a car that I liked he was able to have the car transferred in from another state free of charge. I was called when the car arrived and made an appointment to check it out and I made a purchase.
Love it so far
Special. A delight to drive. Love the way it handles. Extremely responsive, both acceleration and steering. Cabin is very quiet and at night almost too relaxing.

Poor and deceitful.
Poor and deceitful. Gave me an impression of a car in good condition but later found out that what they said was not true. Vehicle had taillight issues, engine oil at 50% brake pads and rotos messed up transmission fluid was not changed either. Car vibrates during stops. I was told something could be worked out if any issues but that is not true. No one answers the phone nor reply to text messages. Both the finance manager and the salespersons lied to me and that's not good for a business. Now i am stock with an issue that could have been avoided in the first place had they told me the truth.
Perfect for the family of 6 like me.😍😍😍
I have this car for almost 6 years I have no major problem at all. We always use this for long drive and short heavy cargo. Excellent SUV.

You get what you pay for
We are in our first five months and I seriously believe all the safety options have kept me out of at least two accidents. The car on the highway practically drives itself while giving me a message. Audio systems are excellent. The 450 GLS makes driving a bit of a joy.

On 8/23/25 After an exhausting search, we were blessed to be connected with Lloyd (Lincoln side) of Hennessy Ford Atlanta. We were looking for a specific used car I saw online (that we learned was located on the Ford side) but our GPS took us to the Lincoln side. The entire process from start to finish went smoothly and Lloyd made sure we felt valued every step of the way. I experienced a level of customer service with Hennessy Ford that is definitely lacking at other dealerships.(If you've ever been to Gwinnett Place Nissan you understand). Even though it was a used car and not their brand, Lloyd still thought it not robbery to call us to see how things were going with the vehicle. Now, that's service! I highly recommend Hennessy Ford and Lloyd to anyone needing a new or used vehicle.They really do care about their reputation!
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.

I bought a Nissan “Rock Creek” Pathfinder from Samuel at Gravity Motors, and had the GREATEST EXPERIENCE EVER! He, and the whole time were so very nice and accommodating! I will definitely go back to Samuel when I buy my Daughters Lexus!!! 5 STARS!!!👍🏼
Large yet stylish enough to carpool the Grands
We just bought this car. Comfortable, roomy, easy to drive. Not quite a luxury ride that the Lexus GL has but performs well. Takes a second to get comfortable with the bells and whistles. Beautiful car, 2 2 2 seating. Easy for kids to get in without climbing over or moving a seat. We bought this SUV for me to drive around town as well as to school carpool my grandchildren. So far...very pleased. This is my third Mercedes. My only complaint with Mercedes is the fuel tank on the passenger side. I feel a little more vulnerable being on the opposite side of the driver side when pumping fuel. I assume it has been this way for years. I guess safety at the gas station was not as big of a concern as it is today. If considering a luxury SUV test drive. I think you will be pleased/

Highly Professional and Honest Staff The team at Cobb
Highly Professional and Honest Staff The team at Cobb Luxury Cars was extremely professional and honest. They helped me purchase a beautiful Lexus ES350 with a reasonable down payment. I also got a 4-year extended warranty through them, and when I needed to file a claim, all the repairs were fully covered with $0 out of pocket. Big thanks to the Cobb Luxury Cars team for making the entire experience smooth and stress-free!
3 month review
I purchased the vehicle off of a lease in March with 60K miles. Overall I am pleased with the purchase. For the size the SUV is very nimble. The surround camera is a must. On a 350 mile round trip my 5'6" daughter-in-law had no issues sitting in the third row. I put the car seat for my grandson in the 2nd row drivers side because lifting the 2nd row back after 3rd row access is cumbersome and heavy on the drivers since you have to lift the middle seat as well. MB you have to make the 2nd row power back to upright position. Adaptive cruise control is outstanding but keep in mind you have to get the Driver Assistance package to get it. Harmon/Kardon surround sound is very nice. My big complaint is sometimes at speeds above 65 MPH there is front vibration. Does not happen all the time, sometimes I can cruise at 80 MPH and feels like I am sitting in my living room. I think it may have something to do with the Pirellis, I plan to switch very soon to Michelins. A very classy, roomy and comfortable SUV

Overall good experience.
Overall good experience. Hakeem was great to work with and made the process feel casual. Some troubles arose that extended our wait but in the end we got the car and the deal we wanted. Thanks Hakeem!
Almost perfect for luxury family truckster
Owned this suv for 15 months purchased certified preowned with 33k miles and about half the price of new. The truck has only two issues to note but otherwise rides, drives and in all other respects is far and away the best automobile I’ve owned - which saying a lot for an old guy. The standard tires are nearly useless in snow and ice and we hope an aftermarket replacement will address the issue later this fall. The more annoying downfall is that although the ride is otherwise amazing, the truck handles sharp bumps very poorly - almost the feeling of a car with workout struts. I have had the struts replaced under extended warranty but the improvement was marginal. For most drivers the suspension issue wouldn’t likely be as much an annoyance but for my fellow ocders, be warned. I would buy the truck again, however.

I found my car on the internet and scheduled a test drive
I found my car on the internet and scheduled a test drive with Kiara. I was her first potential customer. She did a great job even though I might have scared her on the test drive. I ended up coming back after I sold my truck and was able to work a fair deal after some good negotiations. Part of my negotiation was to bring my car back and have a few things fixed on the car that I wasn’t happy about. After about a week, I was able to bring my car back down to drop off for a few days while the work was being done. I worked with their finance guy Keon. He lined me up a loaner to drive while they had my car. After about three days, the work was done and I went to pick my car up. I was very pleased with the outcome and they even fixed a few other things that we didn’t agree on but new I had questions about. They listened to me as a buyer and were willing to work with me. If you want to avoid big dealerships, they have a great inventory up nicer cars and are great to work with. I will shop with them again!
High Performance And Comfortable Car

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!!!
The vehicle was a good experience for the first ti
The interior was very comfortable and the color combination made the experience very nice , was very surprised by the power that came from the engine
