As always Dennis was able to make a great sale. The purchaser got the product he wanted at the cost he wanted. Trade in was fair. Financing was easy. The one problem with the vehicle was disclosed and remedied before the buyer left the property. Great place to shop if your looking for a cehicle.

United Auto is the best. They have helped me get my second car and they are overall really nice and eager to help. They did not come across trying to push you out the door with just any car they are patient and hardworking. I like that they made sure the car I purchased was really something I liked before we went ahead and did everything to get the car. I traded in my older car for another pre owned car and I'm happier with what I ended up with now. Thank you United Auto!

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".
