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

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.

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.

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.

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.

Great Experience
Everything went smooth and easy. The salesman explained everything in detail and took the time to answer all of my questions. I did not feel pressured in any way to purchase a vehicle or any other services. I received a couple of followup calls to assure that I was totally satisfied with the vehicle and the service.
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!
