So comfortable and easy to work with. Felt like it was exchanged between someone I have known for a long time. Very accommodating with my schedule.

2025 GMC Sierra 2500 AT4 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.

Five Star Service!

I drove right in, the Service Associate that greeted me was very polite and explained exactly what was going to be done, as I waited for my vehicle he came to check on me and asked if I had any other questions or concerns, it was a great experience and I will certainly be returning to Transwest GMC for all my service needs

I recently purchased a car and was very pleased with the professional and knowledgeable service from my salesman Scott Halpain. He showed me how to work all the features on the dashboard and explained the paperwork to me. The rest of the people I worked with were also very helpful.

2024 GMC Sierra 2500 Denali review

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.

We had the absolute joy of working with T while we bought

We had the absolute joy of working with T while we bought our vehicle. T went above and beyond in so many ways - by coming in on her day off to help us out, adjusting her schedule to accomodate ours, being open and honest about the vehicle we purchased and the dealership itself - she was able to answer all the questions we had. We even had a small issue (no one could have known at the time of purchase) pop up a week or so after we purchased the vehicle and T was able to get it fixed for us, no problem. And - you know how buying a car usually takes all day? Not here. It took less time than any other place we have bought a vehicle, which is amazing. Thank you, T! You are the best!

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.
