I bought a new 2026 Colorado Trail Boss from Kevin Jones
I bought a new 2026 Colorado Trail Boss from Kevin Jones at Weber Chevrolet in Granite City IL. i felt I needed to write a review since I had such a pleasant experience. First time i can remember having a relaxed no high-pressure sales representative. Kevin was a straight shooter and was great to work with. I felt he dint try to talk down my trade in and was very professional. We came to what I felt like was a fair deal, and he went the extra mile. Set up all my phone and OnStar, brought me a water, helped me move all my stuff over to the new truck. I honestly felt like he wanted me to have a pleasant experience, and I did. This guy is 5 star
The hidden gem Buick Encore GX
I know that here in Northern California, Buick isn't a very popular brand, but that means I was able to get a stunningly good deal on my new '23. I traded up from a low mileage '18 Buick Encore (not GX), and at the time of the transaction, it had a remarkable trade value. My dealer did a outstanding job on pre-sale prep and delivery. My sales rep answered my every question. I enjoyed the prior vehicle, and feel this new one will give me the same kind of driving experience. My added safety feature is the front accident/pedestrian avoidance and lane keep assist. I haven't had to use either yet, but feel good about having them aboard. This Buick strikes me as a hidden gem, full featured but still available at a price point that blows the other comparable Asian built imports out of the water.

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.
no reason to complain
Bought this Encore about a year ago its a 2015, we have driven it daily and just cant find a reason to complain. Its not a race care with its1.4 engine so don't expect it to be fast off the line or on the highway Good on gas handles well, again its not a sports car, just a reliable get around vehicle, one thing very small cargo area

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
Bought 2016 used with 55k on it 3 years ago.
Bought 2016 used with 55k on it 3 years ago. When first purchased had transmission torque converter issue but got transmission replaced under warranty through dealer and has been amazing car since with no issues. Pretty sharp looking inside and out wish wasn’t so mini van shaped but honestly that’s how we use it. Kids love the DVD player. Definitely happy overall.
