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.

My first time at this location and was a bit concerned
My first time at this location and was a bit concerned b/c it was crowded however that is the norm and they are used to it. They handled the crowd with ease. They got me in and out. No complaints regarding my service rep, nor the job performed on my car. Will be returning for sure.
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.

The customer service was great.
The customer service was great. I have tow complaints: 1. A 3% surcharge when using a credit card which everyone pays with. 2. The waiting room was freezing. I know it?s extremely hot outside but it was very uncomfortable in the waiting area.
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. :)

I was looking to upgrade my truck and met Nolan Knox who helped me look for the right truck. He was patient as I tried to make the best decision for me. He responded to all my questions even when he was off. I would recommend Nolan to help anyone with car or truck buying from Carl Black GMC of Roswell.
