Almost glad I broke down so I could meet some of the most
Almost glad I broke down so I could meet some of the most friendliest people on the planet, if everybody gave service like that, they would be a lot more smiles around. Thank you very much for your kind polite service. The only shame is they don’t have 10 stars to give you.
This is a luxury suv with plenty of room.
This is a luxury suv with plenty of room. I'm still learning the features. It is a smooth ride with a great interior. Great for towing a popup camper.

Had a great 1st time car buying experience! They made it a stress free process for me. Enjoying my 2017 Nissan Rogue and have zero issues with it so far!
2021 Yukon XL Denali Diesel 3.0
This Yukon XL has exceeded our expectations. We upgraded from a 2014 XL and it's like apples and oranges. From a size standpoint, the new design allows my 6'6 son to sit in the 3rd row. Not possible on the 2014 xl. Also, they have upgraded all of the finishes and with the new 10 speed tranny the XL drives and feels amazing. We also opted for the 3.0 diesel as that's what was available. We didn't even test drive one as they are hard to find - but man are we happy with the engine, gas mileage, and just how quiet it is. In city driving we're getting about 22 mpg, and then on highway expect to get about 27. Safety features and heads up display all work great. And, the sunroof thing is amazingly huge. Well done GMC and I highly recommend the Yukon XL to anyone that needs to move people in comfort. :)

Easiest Car Purchase To Date
I was searching for a new/used car. I used Cars.com to search for a Toyota Highlander. Carmax in Ft. Worth, TX was one of my choices. The car shown online was EXACTLY as shown when I saw it-the pics and details provided about the car were so accurate, there wasn't a need for alot of "wheeling and dealing". I emailed Carmax regarding my interest, late at night. Not only did I receive an email within 1 hour, the next day I received a phone call from Mr. Ben Arbour, the person who would eventually sale me the car. He walked me through their process, got me pre-approved over the phone, so that all that was left to do when I got to the office was to get the trade-in value on the car I was trading, test drive the new car & sign paperwork to purchase. I bought a 2010 Toyota Highlander that was a 1 owner car with approx. 13,700 miles. I recommend Carmax to anyone looking to get another car. They were great!!! The customer service is GREAT!!!
Beautiful riding truck
Love the truck, lots of bells and whistles, smooth ride, satin Steele is a beautiful color. The Denali has lots of space for my four boys.

Great car buying experience
We were very pleased with our experience. Don was very quick to return my initial communication. He explained the procedure for us meeting and had the car ready for our examination. All care was taken to insure the cleanliness and contamination free condition of the car. The procedure for purchasing the car was smooth and followed social distancing standards. We could not be any happier with how we were treated.

Not our first time here. They were able to get us to drive 2 1/2 hours to Frisco to buy an Explorer that we had decided to wait on. Great jobs guys. I think this Explorer will be a fantastic addition to our life.

Sewell Cadilac of Dallas was Outstanding. They treated us like an old friend. The whole experience was pleasurable and quickly handled over the phone. All of the details and paperwork was done when we arrived. They took time to explain all of the new vehicle's controls, features and warranty issues. It took about 5 minutes to sign the paperwork on the purchase and we were on our way. i

AutoNation CDJR North Richland Hills performed an oil
AutoNation CDJR North Richland Hills performed an oil change and tire rotation and state inspection on my 2023 Ram 1500, July 25, 2025. The service reps all seem very professional. They offered me their shuttle service and had my truck done in about 2 1/2 hours. They did a great job! However, I noted that the tire rotation was not performed as per the manufacturer. All they did was move the fronts to the rear and the rears to the front. In accordance with the 2023 Ram 1500 owners manual the rear tires should have been crossed when bringing them to the front. The other noted issue I thought was huge safety issue, especially driving at night, was that for some reason the mechanic had turned my headlight switch to the off position. Turning that switch to the off position cancels every automatic function for your dash lights and center cluster (infotainment). By selecting the off position, ALL the dash and center infotainment lights go to FULL bright making it almost impossible to see anything outside the truck, especially with the 12 inch screen. It also prevents your steering wheel lights from coming on and prevents the high beams from functioning. I didn't know they had done this as I headed to work at 5 in the morning last Monday. I had pulled off the road twice on the way to work to try to troubleshoot the issue. It was useless because I couldn't see with the lights glaring in my eyes. I'm not sure why they had to mess with the headlight switch, but the least they could do is put the switch back where they found it. Would I recommend them to a friend, yes, BUT I'd warn them to verify their settings before needing them. And probably take it someplace else who knows how to rotate tires.
