I recently purchased a 2025 Chevrolet Trailblazer LS, and
I recently purchased a 2025 Chevrolet Trailblazer LS, and I have to say, the experience was incredibly smooth thanks to Becca, Bobby, and Brian. From start to finish, they made the entire process hassle-free and enjoyable. Their professionalism and attention to detail truly stood out, ensuring I had all the information I needed and that the transaction went off without a hitch. I couldn't be happier with my new vehicle and the outstanding service I received! Highly recommend this team for anyone looking to make a seamless purchase.
One of the best looking suv's on the road. Highly
Extremely happy. Ride comfort, controls, comfort, looks, quietness, Quality. They should've kept the 2.0 turbo. But this engine not bad at all. Can't wait to get another.

Jim Schebil (President) was very accomodating and never wavered from original agreement. Our salesman Tom Gackle helped us with ordering and providing a smooth buying experience. We were treated extremely well and I would urge anyone to check with this dealership before signing on the dotted line elsewhere.
Amazing SUV
I’ve had an amazing experience with terrain Denali. I had it for 3 years and it was one of the best cars ever. Everything worked perfectly no issued at all! Loved it

Great service!
What a fun day we had with our salesman, Ron Zontini. He made the car-buying process easy. Despite the anxiety of purchasing a vehicle and the unfortunate demand during this pandemic, we got through it unscathed. It helped that we did our homework. Ron gave us all the right answers to our questions. We drove off the lot with a gently used Dodge Durango. We also traded a vehicle that we were happy to part with!
Grea4 mileage and comfort
Bought it used. The shifter on the dash takes getting used to. But after a month I no longer grab for the shifter arm. Have been happy with comfort. Driving. Gas mileage. Would recommend it.

Great people and Good deals
Smooth Transaction, the finance process took some time but was worth the wait. i like the dealership, and I will come back and recommend others to come and buy.
Try this SUV before you buy another!
Frank Kent in COrsicana, TX gave me a great deal on my trade-in and on my new Terrain! I was intending to by a VW Taos that morning but when I saw the Terrain AT4 and drove it a little, GAME OVER ! I came home in the stylish and comfortable AT4.

Great experience
Our experience was made easy and financially comfortable by Ben and Scott! Ben worked with my requirements and financial boundaries and got me in a fabulous new Buick Envison. Ben is friendly and knowledgeable and stayed in communication with me regarding all things necessary to complete my deal with ease.
