United Auto is awesome! My boyfriend and I were looking for a Ford Explorer and we were planning on later this year to purchase one then my car decided to die on us. We went to United Auto and found a Explorer in our price range. James and Tre helped us and they did a fantastic job. We negotiated the price down and they were more than fair with us. We ended up getting the Explorer and got a great deal out of it. Would definitely recommend to anyone considering coming here

My wife and I where in the market to purchase a new car. Now let me give you a bit of a back story. In 2019 I had to undergo 2 emergent back surgeries. This left me with the inability to work, which put a serious strain on our financial situation. That coupled with over a million in debt after spending a month and a half in the hospital, the end result... Bankruptcy. Our bankruptcy was closed in May of 2020, and we knew we now needed to begin to rebuild our credit. This posed a serious problem, no banking institution would even look at us unless we had been 2 years past our closure. With what savings we had, we went to see our friend at United Auto of Idaho Falls. Dennis Gray (THE MAN) has been a long time friend, and knew what we where up against. Working with us, Dennis was able to find and secure financing for our purchase of the pictured Dodge Grand Caravan. Not only was Dennis able to get my family and I the right car, but pulled what I can only describe as a miracle ...

The Best Used Cars in Idaho Falls

United Auto Sales is owned and managed by Roger Sheehy. Roger has been in the automotive business for decades serving Idaho Falls and Ammon residents. We have learned that our customers value price and reliability in their used cars or used trucks more than anything. That is why we individually choose each used car on our lot to maximize both.

Roger has operated, managed and owned several used car lots, culminating in United Auto Sales off Hitt and Anderson in Idaho Falls.

We travel to car auctions throughout the West to find and purchase gently used cars that will last our customers for years. We also give the most for trade-ins of any dealership in the area.

Let us help get you into a car or truck that will fit your needs at a price you can afford.

Additionally we have a detail bay where we take your car and make it feel new again. Our expert car detailing service will breath new life into your ride, or makes for a wonderful gift for someone that has everything.

So if you're in the market for used cars in Idaho Falls or Ammon then come visit us. You can count on getting the best value for your dollar "on the savings side of the tracks".
