2025 GMC Sierra 2500 Denali Ultimate review
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.

Best car-buying experience I have ever had in over 50
Best car-buying experience I have ever had in over 50 years of buying automobiles. It was simple, straightforward, honest, no-frills (read no added costs), and the large selection meant that I was able to get exactly what I wanted. Online shopping and negotiating was very easy with no surprises when I reached the dealer to make the purchase.

New car buying made easy.
New car buying made easy. The entire deal was completed through email and over the phone. Jason Davis was friendly and helpful. He answered my questions in a timely manner and made the experience simple and hassle free. The vehicle price was straightforward with no haggling required. I felt like I received a very fair trade in on my truck.
