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.

Purchased a 5.9 Diesel Cummins from Carma. They have a big selection of diesel trucks that are rust-free and low miles. I will be returning to them as I grow my hauling business.

Wonderful truck. Has had zero problems. I am trading for a new one. Truck is all original with no modifications. Truck is in excellent condition.

I have never been disappointed for over seventeen years for coming to this particular dealership. The name may have change and some individuals have left. But the quality of customer services still expectational in my personal opinion.

One very awesome vehicle. Checks all the boxes you need in a truck and exceeds expectations on quality, performance, and looks great ,too. Love my nre truck.

My previous car completely died and was not worth fixing. As a nursing student I needed a car quickly! With not so great credit, I was worried I wouldn’t be able to make this happen. Jeremy and David were a dream to work with! I found the car I wanted, was approved quickly. Once I made it to the dealership (I live two hours away), the process was quick, painless, and I was on the road in my new to me jeep! Could not have asked for a better experience! It was definitely worth the drive for a fantastic deal on a beautiful low mileage vehicle!

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.

D. Debebe was excellent. We had a 20 minute test drive and it felt like I was taking a friend for a ride in my car. The entire staff was very friendly and helpful. Would definitely come back for next purchase.

Mr. Brian Hastman in the service department was very knowledgeable, and provided very useful information with reference to my vehicle. The vehicle was prepared correctly and is working properly.

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 was having engine misfires with my 2011 Chevy Cruze and brought it to Ourisman Chevrolet. Donovan Hill, my service advisor, clearly explained the issues, the resolution, and the costs upfront. The team had everything fixed (and even washed my car) in under 3 hours. Excellent service!

Maria Pikney at the Ourisman Chevy on Security Blvd site, she is knowledge about the purchase process, through on the Chevy brands Equinox and Blaze and I purchased my new 2026 Equinox Sat Oct 11th, 2025

Excellent service. Employees are exceptional. Even on their day off they took the time to attend to me and be sure that I would find what I was looking for. Lender is very charismatic and professional. I recommend the dealer 100%. Thank you very much Pete and Eric for your excellent service.

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.

Brian was extremely courteous. Made a promise to get work done as soon as possible and kept the promise.

The technician was very helpful and courteous. He provided an overview of the health of my vehicle, which was informative and helpful for me to plan my next maintenance visit.
