Everything ok but my gps audio is not working.
Everything ok but my gps audio is not working. The car is in great shape but there are a get marks on the windows that show it wasn't tinted properly.
An overall nice truck but for a person at my size(5,11)
An overall nice truck but for a person at my size(5,11) the mirrors and posts really block the view. My tinted windows really amplify the problem. The hood also takes a bit of room for a short person. Its a comfortable ride and works well in my line of work in excavation. The sound muffler in the hood makes you think something is wrong but apparently its not.

Colton Biss was our sales rep, and he could not have been
Colton Biss was our sales rep, and he could not have been better! So friendly, professional, and competent. He was very knowledgeable about the car I ended up buying, and thorough as far as going thru the car’s features. He even made sure that I had his personal cell phone if I have follow-up questions about the car. I’d highly recommend Colton and Corwin dealership in Nampa!
I have had to of these before and I drive the xxxx
Just what I was looking for and the price was right. The color was the same as the truck I traded in. We have purchased a bumper pull camper and now mountain passes will feel like flat roads!!

Thank You Ryan Harkins for making it so easy to purchase
Thank You Ryan Harkins for making it so easy to purchase my brand new car. I absolutely love it!! You made me feel very comfortable and you were knowledgeable on every process. Thank you for showing me around and how to pull your vehicle in to have an oil change and car wash. I definitely recommend this guy for your new car purchase. Thank you again Ryan!!!
Big Step Up
This is my first HEAVY DUTY truck and my first diesel. I have only had it a week and 3 days but it has already been on the job and been driven 1500 miles. I expected a much rougher ride than the Chevrolet 1/2 ton it replaced but must say I am pleasantly surprised. I compared ride quality to it's main HD competitors and this GMC 3500HD surpasses them. It has far more tech features than should be expected in a base model but I can appreciate the convenience especially for business. I love that it will project driving maps and directions from my iPhone onto its larger screen. I have not yet towed or seriously taxed its payload but the Duramax diesel is something to behold. Averaging 17.9 mpg over 1500 miles. The DEF fill could be a bit more convenient but putting it under the hood does keep DEF away from fuel filling and is not required often enough to be an issue.

It went well, but I didn?
It went well, but I didn?t get what I wanted for my trade in. Good place to shop for new vehicles. Reputable dealership. I was very satisfied with my purchase.
Unbelievable towing capacity.
The Denali version is absolutely what we was looking for. Towing capacity is awesome. Has plenty of room in back for kids or cargo. Would recommend this vehicle for anyone who tows trailers. Duramax is what they say it is with Allison transmission best vehicle on the market.

Johnny in the service department went above and beyond
Johnny in the service department went above and beyond getting our vehicle repaired. The vehicle wasn't purchased from Transwest but had an extended warranty with it. All of the issues were repaired and part of it couldn't be covered by the warranty. I felt like Johnny worked with us every way he could to make things right !! Thank You
Capable truck with the right options
Drove well and plenty of power, the SLT is perfect for us with the 40-20-40 front seat and without the extras that we don't need that are on the Denali.

Service+
While my car was being serviced on Aug 14, I had a really fun conversation with Ryan. After servicing, I investigated the lot & found a car I really liked. When I was able to, I talked with Dwight Fouts about the car. He figured a deal for me that got that particular car in my garage. My husband & I have dealt with Ferris for about 30 years & I will continue to deal there!
