Very easy process and knowledgeable staff.
Very easy process and knowledgeable staff. Matt Breedlove was a great guy to deal with on my purchase!
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.

I came back!
I came back! This is the third time I?ve purchased a vehicle from Hyundai! I absolutely love this place! I worked with Joe this time around, and I have to say this guy is awesome! He?s so incredibly kind and down to earth. He really wants to help you find what you *NEED.* This deal I worked with Joe, Steve, Phil and of course Karen! I love you all. Such incredible people. Yes, they are a car dealership. Yes, they sell you cars. I initially went in looking for a used bigger vehicle. I was given the option but ultimately Joe showed me new was going to be the way to go. Payment, interest rates and warrant all being taken accounted for. He showed me my budget friendly vehicle and the second I dismissed it for personal reasons he basically tossed the keys back in the building and got me what suited my growing family better! I got the deal of the year. Steve (finance) and I got down to business and he laid it out plainly. He got me everything I asked for and I am so incredibly happy. Phil helped me secure my top quality extras I factored into my deal. I highly recommend Joe and this whole team. I will be back once this baby is paid off
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!!

Justin was easy to work worth, made buying the 2026 truck
Justin was easy to work worth, made buying the 2026 truck quite painless. Very knowledgeable. He was very prompt in returning my phone calls. Would buy from him again.
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.

Ruben Espinoza was extremely helpful, and we will be
Ruben Espinoza was extremely helpful, and we will be recommending him for future buyers. My husband and I had been looking for the right vehicle for our family. Before coming into the dealership, my husband and I were hesitant because we had a terrible experience with other dealerships. Truly satisfied with our purchase and the overall experience of the place. We had clear communication from what we wanted and what was in our budget. Ruben was professional, polite, and went above and beyond to make us feel listened and not rushed to buy any vehicle--took his time and we truly are enjoying our vehicle! I have seen the reviews on here and I can say, I highly recommend Ruben, not just a car salesman but an understanding and knowledgeable individual--who goes above and beyond for his customers!
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.

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

I got a good deal on the car.
I got a good deal on the car. Tyler was great to work with. If there was one thing to complain about, it was the time it took to work things out. I was there for four hours, just wish we could’ve cut down on the time.

Quick response to the initial online inquiry.
Quick response to the initial online inquiry. Appointment scheduled for test drive over the weekend. The dealership even kept the car for me to test drive even though a few other customers inquired about the vehicle prior to my test drive appointment. Experience at the dealership was quick and smooth. Met a couple of good individuals during the process.

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
