We felt heard, respected and valued at AutoNation Chevrolet North. And that?s saying a lot coming from this Ford loving family! James, Joe and Braden made the car shopping experience fun and the buying was smooth. We will check their inventory first next time we need to buy a car for sure!

Austin Ellenberg helped us find the exact Buick Enclave
Austin Ellenberg helped us find the exact Buick Enclave that we wanted. He was very nice to work with and patiently helped us understand all the new features on the 2025 car. His explanations of everything were excellent, and we appreciate his offer to talk with us again about any new questions that we come up with. We also appreciate that he had a new battery installed before we took possession of the car, since the previous extreme cold temperatures had run down the battery while the car was on the lot.
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.

The Quest
Avery was very good he met me when it was convenient for me he also didn't quit looking when I didn't find quite what I wanted he listened and found exactly what it was that I was looking for the financing which was already pre-approved for me was still helpful from their dealership because they got me an even lower interest rate we would definitely go back to the dealership and in the future would buy another one from them
Beautiful truck

I paid over $106,000 for this truck with warranty. Do not care much about miles per gal. at that that price range. Just too much truck for me at my age.

(thats important to me) They , Tammy Wagner and Mike Mathis her manager sold me the truck of my dreams. I plan to be a life long customer with Tammy Wagner at Crown Buick

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.

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

Great car buying experience. Friendly, knowledgeable, no pressure salesman Kyle Berry. One minor problem was handled quickly and professionally with no hassle. Go see Kyle.
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.

Rafeal was my contact there and he was great.
Rafeal was my contact there and he was great. He went above and beyond to communicate share photos and video and was very transparent. As a matter of fact the whole process and everyone was easy to work with. Not the dealer where sale and sale manager go back and forth to do some crazy negotiating. Open transparent and fair dealing. Rafeal was an advocate throughout and in and out with anew car well less than an hr after trade in paperwork

After any serving of a vehicle taking it through your car
After any serving of a vehicle taking it through your car wash before returning to customer. This might encourage more customer loyality. Oil change prices are too expensive. The expertise needed to do that job doesn't equalate to charging that amount.
