Great experience from start to finish!
Great experience from start to finish! Love this service group! Ricky, thank you for your amazing customer service! I look forward to my next visit as this entire team is exceptional!
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.

Great Place to buy a car
I was in need of a new car . The one i had was bought in 2005 but the year of the car is 2001. I wanted something a bit newer and affordable. I didn't catch the guy's name since my dad was the one who dealt with him first. No pressure at all. He was very helpful. I test drove the car and loved how it drove along with it's a big upgrade to what i had. So decided to buy it. I bought a 2012 Infiniti G25x, leather seats, AWD. front seat heaters, sun roof, backup camera, defrost on the side mirrors and it's a V6. I love it. I highly recommend buying a car here.
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.

Great Experience!
My experience with Foundation KIA was nothing short of fantastic. I interacted with several different sales people and the finance manager Nick was outstanding! I will recommend them to any of my close family and friends.
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.

Lindsey and Prestige Audi are 5 Stars!!
We moved to Colorado from the east coast. Needing a vehicle for the CO weather, the Q5 was the perfect vehicle to meet our needs. Lindsey was so great to work with. During this challenging time in purchasing a vehicle, she was knowledgeable and patient with us. We worked with Lindsey to identify which Q5 was most suited to our taste. She researched and worked with another dealership that had the exact Q5 we wanted. We are beyond excited with our new vehicle. During our vehicle search, we visited several other Audi dealerships, but Prestige Audi was by far the most accommodating. Based on our experience at Prestige Audi, I do not see us going anywhere else when purchasing a vehicle in the future.
I bought this vehicle is a retirement car.
I bought this vehicle is a retirement car. He moves great is responsive and very smooth. I wanted a retirement car for my retirement. I am 60 years old and I want that something that represent my current status with luxury interiors, beautiful blue color, and 20 inch wheels it is awesome looking. I can reach 70 in the blink of an eye any moves like it's going at 30 or 40 miles an hour. He has an awesome radio system. although it is not all digital, the radios are for listening. I have an excellent sound, System. Great interiors, great materials, great lighting if you're planning to buy a GLS the 450 is definitely one of your best choices.

Amazing customer service in service department
Bought my vehicle from Golden, CO Carmax and didn't have any support for mechanical issues. Still purchased the vehicle because it is what I wanted. Ashley from sales in Golden was the worst! I ended up closing the deal with Cora who was amazing and clearly the exception to the rule in Golden. When I told Ashley there were issues with the brakes she was rude and didn't take me seriously. I ended up working with the Federal Heights dealership on repairs. Debbie in the service department took this on and was soooo amazing! She took care of everything and I am so greatful! The technican at this location was amazing as well (I forget his name unfortunately)! It is really a shame that I had to go to another location to get service, but I am so glad that I did. Outstanding job Federal Heights location!
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.

I am relocating to the Denver area and getting everything together, house, car, job, etc., has been an intense juggling game. Everyone who helped me with my car purchase was extremely helpful and made me feel so comfortable. Even though I didn?t buy a Mercedes Benz, they still made me feel like I was worth a million bucks!

Niko went far and beyond more than I expected, and I left with an amazing car. Everyone else there was amazing as well and did an awesome job.

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..

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
