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.
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.

Completely satisfied. And happy with this experien
I spoke with Tra Farrow recently at the Alton IL. Location. I was completely honest with him. He ask where I was thinking I wanted my payment to be monthly. I give him my response. I was buying a pre owned vehicle. I bought a Dodge Ram regular cab. He also was completely honest, respectful, of my request. He said he would see what he could do. After talking it was clear that we could complete the sale. I have always purchased my vehicles from private owners. This is the first time I used a dealership. I have this dealership and Tray a five star rating. While I realize it is difficult to get it give a business a five star rating. It was easy to give them the best possible rating. Everyone whom I came into contact with during my visit was outstanding. I was overwhelmed at how easy it was. This business could not have done anymore to change my opinion of dealerships. I know all things do not end this way. If you are in the area of Alton IL. Please give Tra and the staff an opportunity to serve you.
Best Truck I ever owned!
This truck is everything I wanted! GMC, 4x4, Lifted, Low milage. It's going to be great for my hunting and 4 wheeling! I love it!

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.
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!

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

Everything you could ever need

I WAS VERY SATISFIED WITH THE DEAN TEAM AND BRANDY
MY EXPERIENCE WAS VERY GOOD. BRANDY PETERS WAS MY SALESPERSON. SHE HELPED ME AND TOOK VERY GOOD CARE OF ME AND THE CAR I BOUGHT
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.

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.
2020 GMC 2500 AT4
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.

Taking a 12-year-old CTS Sport Wagon to a Cadilllac
Taking a 12-year-old CTS Sport Wagon to a Cadilllac dealership for service tends to make one brace oneself for the onslaught of potential sales pitch that naturally occurs when an older model comes in for service and the dealership is in the business of selling brand new ones. To my pleasant surprise the approach was quite the opposite and Terry, along with members of the sales staff, all seemed genuinely happy to provide service work without the sales pitch. The work was completed quickly and the car remains the reliable and fun-to-drive car that has been a testament to the make's time-honored claim as "Standard of the World". Even when I mentioned that a new Cadillac might be in the cards someday, the staff was happy to know they were helping keep one of the most iconic models that Cadillac has produced in recent years on the road. Thank you, Terry and the staff who worked diligently to get my car repaired and back to me well within the time frame that had been promised.
A Beast when it comes to hauling!
I love how the truck pulls and rides when towing. It will give any driver the confidence to tow anywhere. I haven't had a single issue with it. I love the way it looks and couldn't be happier.
