Thank you for the wonderful experience with the sales
Thank you for the wonderful experience with the sales person and the finance department. The finance of the vehicle was well explained. We always purchased our vehicles there.
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.

I was treated with a respectful and caring attitude. They listened to my needs and answered all my questions with patience. Together we found rhe perfect car for my needs and I am delighted with my purchase.
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.

Outstanding service.
Outstanding service. Worked with Erik for my first oil change in Service. He was super fast, got to the point, gave me accurate time frame for completion and communicated with updates while I was waiting. Also, Robert with customer service was awesome and even offered and bought me a star bucks coffee while I was waiting. Probably best dealership in country.
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. :)

Just bought my second car from Bill Luke.
Just bought my second car from Bill Luke. No games played here. Very straightforward with pricing, knowledge, and listen to your requests. I worked with JJ, Neftaly, Thayer and Eduardo and they all did an exceptional job. 5 stars. Highly recommend using them for your next purchase.
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.

It all centers around Trudy, my salesperson .
It all centers around Trudy, my salesperson . She was persistent and didn?t give up on the sale. I didn?t think we were going to buy from Yates even though the Yukon XL was our favorite of the Suburban and Expedition Max. Trudy really kept coming at us trying to make it work . Finally for me , it was Saturday when she sent me videos and said ? This is the one you drove. I know you and your wife liked it . It is here for you . Let?s make a deal!? Even later in the day on Saturday , I had already test driven another Expedition and Suburban with a diesel . I was not planing on stopping back at Yates but I was driving by on I10 and thought of Trudy?s videos she sent me. .I said , why not , she tried , let?s see. Even after I made a decision on the Chevy Suburban , ( only because it had a diesel ) but the Yukon XL was my favorite and Trudy was the most personable and persistent . Honestly , I was not the happiest with the numbers, everyone else gave me a little more for my trade BUT I liked your Yukon XL the most and we bought it . Also , it has to do with the Trudy being persistent . Even at the dealership getting ready to buy , I was having second thoughts and Trudy sat with me , and we talked while I waited . I almost walked out before the paperwork was ready . . But i really loved the Yukon XL. It had so many features I liked compared to the Suburban and Expedition. So Trudy?s customer service and I really liked the Yukon XL were my reason for sticking to it . Thank you Trudy . In addition , thank you Ramon , the fiance guy, he was patient in signing the paperwork . We were waiting for my wife who was on duty with the Fire Department. Another thing Trudy did right !! There was some issues with my wife at work and trying to sign the paperwork . Liability with me taking the Yukon XL home . Trudy was doing everything she could so i could take it home that night . Again , thank you Trudy !!

Josh Ballard
i recently bought a car from her but my tires were flat and i came to get help. hours spent at the dealership can be awful but out of all the hours i’ve spend there this past month getting my new car this was my best experience yet. Josh Ballard helped me out with getting new tires he was timely on everything and made sure to get the best answers before contacting me. he was so attentive in every detail. this is my first time dealing w a car alone since i’m in az for college. he was unable to get the car delivered to my school and he knew i need to ask for a ride to get to the dealer before i could even respond he had already sent me a lyft pass so i can ride to the dealer! he made sure i didn’t make any unnecessary expenses and he made sure i had my car back to me asap!

The team at Henry Brown is very exceptional.
The team at Henry Brown is very exceptional. Purchasing a vehicle from across the country is stressful but my salesman Mike Roberts made the whole process very comfortable. I have spoken to many salespeople throughout my search for a new truck and am very glad i was working with mike throughout the purchasing process. I recommend henry brown for any of your future auto purchases!
