Best Dealership in Utah
Nate Garza at Jerry Seiner is amazing. I'm sure i bugged him more than my fair share about the arrival of my vehicle. The dealership entirely is all very friendly and helpful. They bent over backwards to make sure i got what i wanted/needed. You can tell they work hard to make sure you keep coming back. Which i will.

Most recently bought out my lease because I had such a good experience. Parker is fantastic, helpful and responsive. The service manager is incredible and goes out of the way to follow up, reach out and ensure I have a white glove experience every time

A great experience buying a GMC 2500 Truck!
Colby made the process very smooth and easy and was at times even funny. No pressure and everything was explained. They gave me a full tank of gas and the vehicle was spotless. Family run business and I will continue to recommend based on my experience.

Amazing car buying experience!!!
By far the least amount of time spent purchasing a vehicle. We knew the numbers, and got all questions answered in a matter of minutes. They brought the car closer to us and had all paperwork ready to go. It only took 10 minutes and we were on the road in our new car. Well done!

We came into this dealership, unsure of which model would be the right one for us. Willie Rahlf helped us test drive a few different vehicles and listened to our needs. We settled on a Tucson hybrid Limited. My wife loves it! We have been to this dealership multiple times over the years and always recommend our family and friends.

Don't be fooled by just low prices - they all pay the same for vehicles. These guys know how to order new trucks with the right packages that won't cost you an extra arm and a leg. Save thousands by knowing how to order the right option packages on your next vehicle. Some dealers don't know how and you either get a truck with too many stupid options or not enough.
