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.

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.
One very awesome vehicle.

I highly recommend this business.
I highly recommend this business. I was completely impressed with Angelo, and the service department. Very knowledgable, reliable and honest. Angelo took the time to answer all of my questions, and provided me with available options from repair to replacement.
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.

Extremely easy buying process
Been looking at used trucks for some time. Trenary in Troy had a vehicle that I was interested in. Contacted the dealer, asked if truck was still there and set up an appointment to come take a look. My salesman had the truck up front and ready for me when I arrived. The entire process (including finance) went very smooth and I appreciate that! Thanks again!
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

Jim and Ken did a fantastic job. They were patient and answered all my questions. They made me feel like the entire dealership was open to me. They introduced me to the service manager. The car is incredible, better than my BMW X5.
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!

Excellent customer service
On July 15, 2023 I purchased a new car from Dean Team Volkswagen in Kirkwood. Eddie was great to work with and made buying a new car painless. We were in and out in no time. Thank you Dean Team...awesome customer service, we will be back!
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.

Dave Sinclair stands by their product.
We have purchased 6 cars or trucks from Dave Sinclair Ford or Lincoln. They have always treated us well during and after the sell. We tried to buy a Chevy EV Bolt this month but the service was so bad we choose to keep our Lincoln instead. If I had not moved to the east coast last year, I would continue to only buy from Dave Sinclair.

Everyone was nice and the place was extremely busy. We worked with Nick who was working with 2 sets of customers at the same time, he did a pretty good job of handling both. We test drove a truck and tried to work a deal, but it just did not get down into our price range.

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 REPUTABLE CAR SALESMAN!
Ed Rapien has been our salesman for 15 years for Ford-Mercury products. He is very professional, sells the cars for a fair price, helps with backing up any problems we have had, & I actually feel he is an honest car salesman.My only complaints are that Ford is no longer making sedans or the Mercury brand. These are not Ed's fault, however. Thank heaven they kept him when dealership was sold from Price-Gnade to Trenary.
Never had one. Always wanted one and love it.
I love my Denali. Beautiful truck inside out. When I drive down the road all heads turn. I couldn't have made a better choice. That's Cortez for you good service.

Mountaintop for life. Awesome experience
Found me a truck that I have been looking for. Had several on the lot but I’m very picky and knew what I wanted. Since they didn’t have the exact thing u was looking for, the salesman spent the rest of the day finding my truck. He went personally and picked it up and got it through service very fast and I was ready to roll with all tests ran and a great truck on top of it. Absolutely would go to this dealership again. Looking for a car and an SUV next year for the family. I will definitely be going back when I’m ready to pull the trigger on my/our next vehicles
Very beautiful truck
This truck would help me thru out my needs I and my family love this beautiful truck, there is no better place for me to shop than the Paso Robles Chevrolet I highly recommend them

Matt is the kind of dealer you had back in the day. I enjoyed the short back and forth we had with numbers and the entire dealership left us with needing nothing, they took care of us further then we actually needed
