Great salesmanship!
Great salesmanship! Willy helped us seal the deal efficiently. ❤️ our new CR-V. Mountaineer Honda Rocks!
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.

Had a small issue but they took care of me. Picked my vehicle up from my place of employment and brought it back to me.
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!!

So i didn't get the car i really still want it i keep
So i didn't get the car i really still want it i keep seeing it 😔😔 i can afford it but I never been without a job more than two years ....but 2 yrs ago I was hit by two vehicles on my job and hadn't worked since 😔 I'm wondering if I could put more money down could I possibly still get this car ....just a thought
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.

The sales associate Shayla was friendly, knowledgeable
The sales associate Shayla was friendly, knowledgeable and professional. The test drive of the vehicle was informative
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.

I felt they were honest 1st of all.
I felt they were honest 1st of all. Can't say that about very many dealerships. They gave the best trade-in value on my 2015 Tahoe (by far). I searched Missouri and Illinois for about 8 weeks and Sapaugh was the best experience Hands-Down. My ONLY fault with my whole experience was getting my paper work finished. It was a cash deal with a trade-in. NO financing needed. But it was a holiday weekend (01/02/2026) only one guy doing the paperwork processing instead of two. NOT a giant deal.
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.

New to us Truck Purchase
Juan is the Greatest sales person you could ever hope for, he was very patient with us and did everything he could to get us into a New truck for my wife. We did end up purchasing a 2017 Ram 1500 and are very happy with our purchase. Could not have asked for a better place to get a vehicle from

Purchased a 2024 Ram 2500.
Purchased a 2024 Ram 2500. The sales staff was excellent to work with and very personable. I would recommend doing business here and will try to in the future. I flew there from Nebraska to make this purchase and was nervous. When I got there I soon realized I had made the right choice. Sales personnel were not pushy and very down to earth and didn’t not try to force anything on you that you did not want. After I bought the truck I jumped in it a drove home six hours with no regrets and no issues on the truck I picked.

Salt Lake Valley Chevrolet, the best dealership in
I have been a customer for about 12 years. The dealership has sold me 2 compact cars. One truck and a 2016 Chev Equnox. This car has been my favorite. This dealer is the best in the State. I have all repairs and maintenance done there. They are superbly courteous to customers and do excellent work. I always get my vehicle back when promised and the have always done the work I have requested. I will continue to purchase my vehicles from Salt Lake Valley Chevrolet. Thank you from a very satisfied customer Sincerely. Stan Parkin
