Ask for Herbert!
Ask for Herbert! He is the best! He is very friendly, knowledgeable, and personable. He made trading and purchasing much easier! I would buy from Autonation again 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.

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. :)

No pressure No games Easy buy of a cash car.
I went to buy a cash car. I had a price range to follow. I looked at a Lexus 07 LS460. I was helped out in getting a deal for this car by Jesse. I had some some request to be addressed first, to make me feel better about the deal. I saw they where all made. Maybe not to a high standard but they were done. The whole process felt easy with no pressure. I never believed Jesse was playing games with me. Ever. All in all he sold me a car I wanted and at the price I wanted. What more can you ask for? It's a 07. It's got issues. Yes. It's a used car but the buying experience was never an issue. Would I go back to buy another one? Yes. Will I tell a friend? Yes. I just recommend you do your own research on the particular car your looking at. I did not and still got a good deal. Ask for Jesse.

Just bought my new 2026 NX350h from Lexus and had an awesome experience with Nicholas Hughes. He made the whole process super chill and easy; really took the time to listen to what I wanted and helped me find the perfect car. No pressure, just solid advice and great customer service. I Definitely recommend Nick if you're thinking about getting a Lexus." Also, a special mention to Greg who helped my cousin and I with great advice on purchasing a car. Thank you both for this wonderful experience.
