Welcome to Rimrock Auto Group

Rimrock Auto Group is here to meet each of your automotive needs by providing friendly service, precise attention to detail and, of course, a superb selection in all of our car dealerships. Whether you're in the market for a new Mercedes-Benz, Chevrolet, GMC, Subaru, Cadillac, Volkswagen, or Kia model. We also have a great selection of used cars, and replacement auto parts for all makes and models. Of course, if you just need a quick oil change, be sure to take advantage of our highly trained technicians.

The first thing everyone notices when they walk into our car showroom in Billings is that shiny factory finish on all our models. And if that alone can capture your attention, just imagine the feeling of taking a seat behind the wheel for a test drive. That's something we encourage everyone to do. That, and asking questions. After all, we could talk about new cars all day, and often do.

Interested in a used car or truck instead? Well, Rimrock Auto Group has you taken care of as well. We know that top-of-the-line quality and reliability are key selling-points for any automotive purchase, new or used. With that in mind, we work tirelessly to ensure all of our used cars measure up to our stringent standards before they make it onto our lot.

If you have any questions please feel free to contact us, and we will be happy to answer all  your questions as quickly and accurately as possible!
