Car buying was easy with them and they were upfront with
Car buying was easy with them and they were upfront with their price and total out of the door price. Sales person and sales manager were excellent to communicate all the details we need before we make the purchase. Will buy a car from them again in future!
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.

Very good and courteous staff. Had difficulty locating my appointment but all went smoothly afterwards. Picked up my car in no time. It is always washed for me!
Updated model
Read many reviews and researched this vehicle and that helped me decide on this vehicle. Traded in a older suburban for this updated Yukon. Look forward to driving it.

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. :)

Best Car Buying Experience Ever!!
Jose the Sales Manager listened to what I wanted and found the vehicle at another dealership and brought it over. Briana in Sales showed me all the features and explained how everything works. She even helped me get the app set up on my phone. David in Finance was so friendly and made the process easy. I have told all my friends how nice everybody was to me and this was really a no-stress day. I love them. I wish I could buy a new vehicle every year so I can go back over and over.

Mark England is Dedicated! Shop Here
Usually, when you have a bad outcome, people bash the service provider, but not in this case. I wasn't able to get approved without a down payment for a car. But I would like to take out the time and Thank Marcus England from the upmost, for the outstanding customer service, he has been giving me for the past 2 weeks. If you ever need a car, with challenging credit, please contact CarMax Fort worth. Marcus and the fantastic Finance team tried very hard to get me approved. I didn't get a car but the Customer Service shows that CarMax out value in there employees. Thanks so much, I pray Gods Blessings at this place, and that y'all sale 75 cars this weekend.

Sewell Cadilac of Dallas was Outstanding.
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
