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. :)

Carl Miller answered questions I forgot to ask.
Carl Miller answered questions I forgot to ask. Straightforward and not pushy, very refreshing. I would buy from them again. This was an out-of-town purchase and it was a piece of cake to get the job done.
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.

We had a straightforward, no hassle, seamless car buying
We had a straightforward, no hassle, seamless car buying experience at Ewing. Our salesman, Clayton, made the entire process easy for us from trading in our ?problem vehicle? to finding us the exact car we were looking for and having it delivered promptly. There were no salesman tricks, no hidden fees and no pushes to purchase extras we didn?t need. All around great experience. Highly recommend!
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.

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

Love me some Five Star Ford!
My wife's 2017 Edge Titanium needed service because the "wrench" light came on. Dropped it off and met with Odie Terry, our Service Advisor. Odie informed us that it will be a day or 2 before a tech could get to it because they are always so busy. Odie called me a couple of days later and said the battery wasn't getting enough volts to the sensors, creating numerous error codes. Replaced the battery and one code came back as a torque converter issue. Once we found out they would be keeping it awhile Odie arranged a rental car for us. Turns out the transmission needed a complete overhaul. Thank God for the 5 year/60k mile power train warranty, which covered everything! Took about a week but once we got it back it drove like a dream! Odie called me every 2 days to give me a progress report. He made what was a major inconvenience much more bearable. It's nice to know there's a dealership close to us we can totally trust to service our Edge and do everything right. Hats off to you Odie Terry, you are a true professional and an outstanding ambassador to the Ford Motor Company!
There are 20 matching cars close to your year range.
