Had trouble getting my car after service.
Had trouble getting my car after service. I was waiting on my car but they parked it in the lot. Had to wait 15 minutes for them to find it. Had my air filter replaced but they didn?t reset it.
I have enjoyed my vehicle.
I have enjoyed my vehicle. It is comfortable and drives very well. I like the color also. It is very roomy, takes off fast and the safety features are very beneficial.

Very enjoyable experience from walking in the door.
Very enjoyable experience from walking in the door. All that were in the showroom greeted us as we came in the door. Our salesman met with us and showed us the truck we had inquired about. We looked at the truck, wanted it and went in to begin the process. The Manager Steve, came and introduced himself along with our financial manager Kirk. The entire purchase was about an hour and a half, but some of that was learning about their families and sharing stories. Like we were all family. So would I recommend Auto Nation to others, absolutely. This is the second purchase we have made from Auto Nation, the other being located in Amarillo. The staff there were all just as polite and courteous as the Gulf Freeway Staff. Excellent David Willis ?Happy Customers?
3 years with a loaded 2021Yukon Denali deisel
I own a 2021 Yukon Denali with 23K. At nearly $90k, I purchased every option except for the silly entertainment screens fastened to the back of the front seat headrests. (nice for leaving the imprint of your passenger's faces on the screen in an accident - buy a couple of iPads. First of all, kudos to GM engineers. Technology actually exceeds German cars I've owned. Rear view camera is GREAT and adjustable for brightness, distance and width. But, make sure you purchase the washer for the rear lens...Miirror is almost unusable in rain..(blurring with rain and dirt quickly. I'm 6'2" and really ticked-off there isn't a handle on the "A" pillar to grab to pull into the driver's seat. They put a handle at the upper center of the door opening. What is that for? I have to grab the steering wheel (fortunately rigid with the engine off). Another big problem is the loss of both knees in a frontal accident. With the steering wheel all the way back, I can't even come close to stretching my leg out. Really! A couple of bigger issues: I know the front of this vehicle is right off of the truck, but the end result of the gigantic, unsloped hood, is the inability to see anything 12 feet in front of you. And making right turns.....better memorize that curb before you start your right turn because you won't see it again. Just "that look " from your wife as you run over the curb again with your right rear wheel. Lastly, I hope someone from GM reads this.....With all the awesome high-tech items on this car, why are there no "turn" lights? You know, the lights that let you see where you're going, especially right turns. Porsche has LED lights designated for turns that light up the whole area you're turning into. In the Yukon at least I'll see what I ran over with the terrific rear view mirror! My only intermittent mechanical annoyance is when I push the door handle to lock the doors. It's supposed to fold the mirrors in which is a good way to check you locked the vehicle. occasionally , they don't fold and I have to push the button 4 times. Of course, the mechanic needs only to push the button till it works and tell me it's working. Twice. Guess they win. I'll live with it. Now for the rest: Fantastic overall vehicle! With the air suspension it rides better than Mercedes or Lexus. I always get positive remarks from passengers. The steering wheel control for the Active Cruise control is absolutely perfect. I've driven between Arizona and Colorado without taking my hands off the wheel (just moving my thumb). And the engine, I LOVE THE INLINE 3.0 DIESEL! Almost got the 6 liter but took a chance on the diesel that just came out (in 2021). Same exact torque as the V8 and great for passing. The big difference ..... I had to take a photo of my dash to prove to my friends....heading back to Phoenix with 256 miles on the odometer averaging 30.2 mpg going the speed limit! My Porsche Cayenne gets 19.6mpg (not going the speed limit). The 9 cameras help when parking unless your wife is with you. When I come to a stop I'm waiting for my wife to hold up the 1 to 10 signs like the judges in the olympics. And lastly, For a car that will raise 5" in 4 low, why does the car come with 1 ply polyester sidewalls ? I'm not comfortable on gravel or rocky roads for fear of a sidewall puncture. I highly recommend this vehicle. The designers did a great job making this big vehicle look sleek and smaller than it is. I'm a bit unnerved when I see a vehicle like mine come flying into a parking spot for a perfect 4-point landing and the driver is a 110 lb soccer mom. And I just spent 20 minutes with a micrometer adjusting my position so I don't get "that look" again from my wife. Good luck and hope it's reliable.

Awesome buying experience!
First time at CarMax and after a nightmare experience at a local dealer, was a bit wary, but VERY pleased. Reci was an AWESOME salesman. Answered all questions and made the process a breeze. Highly recommend this dealership!
Nice ride
Love the exterior body lines, the front sits a bit higher than the rear, nice stance. Factory aluminum wheels are very nice. Power rear gate heated steering wheel and heated seats are nice as well. Have had dual exhaust installed, the 5.3 sounds awesome. Exterior is white.

Gwendolyn made this service experience easy and less of a to-do. My first service after purchasing wasn’t cold like other dealerships I’ve been too. 10/10
Perfect large suv
I absolutely love my 2021 Yukon Denali. The turning radius is surprisingly good and it handles beautifully. I traded in a 2021 Lexus GX460 for it and have no regrets. This handles way better on the interstate. It’s like floating along on a cloud. I have almost 19k miles and haven’t had a single issue or recall. My son plays his Xbox on road trips in the back seat on the headrest tablet and uses the outlet back there. I ordered the gmc weather proof floor mats and they are way nicer than weather tech. You can comfortably fit 3 adults in the 3rd row. The 2nd row has 42” of leg room which is more than anything else in its class. I drive mostly in the city and average 16.2 mpg. Treat yourself and buy the Denali.

Excellent Car buying experience
I recently bought a Mercedez S550 from Justin Seureau . The entire sales and after sales process was very professional, pleasant, and efficient. I am really happy with the service i recieved. It felt like family the way they took care of me. Justin, the sales director, helped to guide me to the car and test driving it I ended up buying; and also took his time to explain many features of the car; and Chad a very smiling face made the financial part pleasant and quick. if you want the best buying experience of buying a luxury car, go see Justin , and he will make you feel great about your choice to buy your car. They have the best well maintained cars i would recommend this dealership to everyone. They have owned my business for life and i will recommend this dealership to all my friends and family as well. Thanks again Justin for your excellent customer service.

Exceptional customer service. My Salesman Doyle and his Manager Zack listened to my needs and got me in a vehicle that was exactly what I was looking for. They were very helpful and not at all pushy.

My experience with the sales consultant Chris Hennis was above and beyond excellent customer service. Chris explained each and every step of the process we would go through from the test drive to the purchase of the vehicle. Nothing was short cut throughout my visit with Beck & Masten Buick GMC North. I will be recommending both the dealership and Chris to everyone I know that?s buying a vehicle.
