Kind service
Great people at this dealership. I worked with Pete and he gave me no pressure service. I’m waiting a few weeks to buy a car because I’m traveling soon, but Pete was kind and helpful and I will be going back to him to buy.
One very awesome vehicle.

Easy process.
Easy process. Dmytro was very helpful and accommodating. Follow up was timely. Found the car I wanted online, submitted a request for information, received a call back immediately.
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.

Entire family has a car
Brought my daughter to look at a new car. Put her in touch with Brook Winter. She walked away with a new GMC Arcadia. She is so very happy with her new SUV. She also was so pleased at the service she received from the time we entered the door until we left 3 hours later. We now have 2 Cadillacs and now she has her SUV. Will always recommend to someone looking to buy.
Beautiful truck
I love my 2021 GMC Denali 2500HD. I have gotten more complements on this truck than any other vehicle that I have owned. I get great highway fuel milage average 19-26mpg,which is great for a heavy duty truck!

Nikki was extremely professional and knowledgeable about the trucks. The buying experience could not have been easier, and I never left South Carolina! My new Denali Ultimate gets delivered today at 5!
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.

I just purchased a 2016 pre-owned Toyota Tundra
I just purchased a 2016 pre-owned Toyota Tundra from Jim Trenary of Troy. When I sent off the inquiry from Cars.com about the truck, I had a sales rep respond within 2 hours with all the details of the vehicle. The sales rep was friendly and knowledgeable about the vehicle. I ended up setting up a time to look and test-drive the truck. It met my requirements and I ended up purchasing the truck this past weekend. He made the whole process simple and easy.
Best truck I ever owned
Love my GMC. Owned a Chevy and this absolutely beats it hands down. Never had any issues. Inside is very comfortable and can't imagine driving anything else

GM RECALLS ABOUT TO LOOSE CUSTOMERS
I made appt. For recall parts however after making that appointment, and leaving car there for 2 days, was told no parts for repair available. They are available in Florida so it appears I should have had it done there. Bought two cars from this dealer and have always been pleased until now.
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.

Quincy
Great experience at Carmax at Mid Rivers in St. Louis. We were looking for a low mileage 2014 Toyota RAV4 and we found the SUV we wanted on the lot. In total it was the fastest we have been in and out of a dealership after buying the SUV.
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!

Great Experience
After putting off looking for vehicles, as in the past it was usually not a pleasant experience, we stopped at Behlmann GMC. We were fortunate to have been greeted by Doug Johnson. Doug is very knowledgeable and easy to work with. In fact, we ended up buying two vehicles. We recommend anyone thinking about buying to go see Doug.

I recently purchased a car from this dealership, and I cannot say enough how wonderful the experience was! From the moment I walked in, I was greeted with a warm and friendly welcome that immediately put me at ease. Every step of the process was smooth, straightforward, and stress-free. The customer service here is nothing short of fantastic. The staff was knowledgeable, patient, and truly seemed to care about helping me find the right vehicle. Special thanks to the general manager, Scott, who went above and beyond to make sure everything went as smoothly as possible. He made what can often be a stressful experience feel easy and enjoyable. I would highly recommend this dealership to my family and friends because I know they would have a great experience, just like I did.
