Getting a car at Autonation Katy was a breeze.
Getting a car at Autonation Katy was a breeze. Justin Hernandez actually introduced a better car for better value than the one we were originally looking at, was very knowledgeable and answered every question patiently. Great guy to work with!
Great Truck
I paid over $106,000 for this truck with warranty. Do not care much about miles per gal. at that that price range. Just too much truck for me at my age.

I want to take a moment to recognize Anthony Alvarez at
I want to take a moment to recognize Anthony Alvarez at Group 1 GMC Buick South for an outstanding car-buying experience. I came into this process already approved and funded through my personal bank, fully prepared to purchase a 2024 Ram Laramie elsewhere. Unfortunately, the lack of professionalism at that dealership led me to walk away at the last minute. Walking into Group 1 GMC Buick South was a breath of fresh air. Anthony immediately stood out ? not as a typical salesman, but as a genuine, respectful, and knowledgeable professional. Anthony is a former Marine, and as a Navy veteran myself, there was an immediate sense of mutual respect and straight-forward communication. He was down-to-earth, transparent, and never once applied pressure. He listened to what I wanted and helped guide me to the right decision based on my needs ? not just the sale. Because of Anthony?s professionalism and integrity, I confidently purchased a 2023 GMC Canyon, and I couldn?t be happier with my decision. In an industry where honest salespeople are hard to find, Anthony is truly the real deal. If you?re looking for someone who treats you with respect, communicates clearly, and genuinely cares about doing right by the customer, ask for Anthony Alvarez. Group 1 GMC Buick South is lucky to have him.
Great Truck (sans MPG)
Love everything about this Duramax Denali except the fuel mileage. 13-14 Mpg tops when not towing. Bought truck cause previous was stolen. Wish I still had my 6.2 High Country!

Best truck I have owned
I've owned every other American truck and this is my first GMC. I bought the 2500 HD Texas Edition. I absolutely love this truck. It's everything I could have hoped for and more. It is able to pull my 30' travel trailer with no problems. So now when we go out with our trailer I'll have no worries. The look and feel of the truck is outstanding. The 6.6L gas engine actually gets great gas mileage. It gets about the same as my Ford f150 ecoboost. Probably better on the highway. Looking at about 13 miles in the city and 15 plus on the highway. Definitely got a better truck for the price compared to any other american models with the same characteristic and options.

I had a great experience at AutoNation CDJR Katy.
I had a great experience at AutoNation CDJR Katy. Rafael was my sales rep and he explained everything clearly, answered all my questions, helped me feel at ease about any doubts I had regarding making a big purchase, and worked hard to make sure I felt comfortable with the best deal they could possibly get. Gerardo in finance was just as great. He was knowledgeable, very easy to work with, and even made signing paperwork fun. The whole process was smooth and efficient! But what really stood out to me from this dealership was the degree of professionalism and honesty. When an issue came up, instead of brushing it off, they were upfront and fixed it quickly. That kind of integrity and proactive protection of customer trust is rare. And it?s the reason we?ll definitely come back here for my husband?s car and my next car, as well as refer my friends and family, because outstanding customer care like this deserves to be shared and celebrated. If you want an honest dealership that treats you with respect, values transparency, and truly cares about its customers, AutoNation CDJR Katy is the place to go!

This truck is the truck that all others should look up to. It rides great, will tow a house, runs smooth, and gets great fuel economy. The Allison transmission is so smooth. The AT4 looks great too.

I purchased a 2005 Corvette over the phone. The car is in excellent shape low mileage and the experience of buying this vehicle was hassle free. Also had the car shipped to Las Vegas Nevada no problems. Would purchase another car from unique Auto again.

What a gorgeous truck, runs good, sounds good and has all of the amenities I need although I am looking forward to their next interior upgrade.

As with many auto dealership experiences, my interactions
As with many auto dealership experiences, my interactions with Shottenkirk Nissan had its ups and downs. However, I am giving 5 stars because there were two people that made the experience that good; our salesperson, Sommer, and the GM, Harmon. These two went above and beyond to answer questions and make us feel like our business was important to them. I highly recommend visiting the dealership to purchase from Sommer. She never pressured us or made me question whether she would just say whatever I wanted to hear to buy a car. She was honest, polite, and helpful. That is something that most salespeople lack greatly. Harmon assisted in the finalizing of the deal by being genuinely helpful during trade in process and answering all of our questions accurately about fees and taxes that appear on the buyers order. He eliminated the tricks and nonsense that many dealers do to grab a few extra bucks during the buying process. Thank you, Sommer and Harmon.

Very disappointed that Sterling McCall doesn't honor the $49.95 price they advertise on their website. This is the second time this has happened. Why even advertise if they don't honor.
So far so good!
So far so good! This truck is the nicest truck I have ever driven. The stance, ride comfort and options are top notch. I went from a 2023 High Country that was having drive train issues but had all the creature comforts that you would expect in a top of the line truck. With the lack of confidence in that particular models 10 speed transmission issues, it became necessary to reestablish my confidence in my General Motors product.
