About Peterson Auto Group

Building a Legacy

It started with a wrench and a dream back in 1923. LG Peterson was fresh out of the Army where he was attached to the Ambulance Core as a driver and mechanic during WWI. The Military had recently deployed motorized ambulances which were replacing horse-drawn carriages and LG had a knack for fixing them. After the war he decided to open as a Durant, Star and Buick Dealer. As Peterson Motor Company grew, LG was offered the Durant distributorship either in Boise, Idaho or Phoenix, Arizona in 1928, and eventually A Hudson distributorship in 1933. He chose to keep his family's roots in Idaho and packed up and moved Peterson Motor Company to Boise--down on 12th and Main.

That same year Marvin Peterson--LG's son--was born and so the legacy began. Marvin would eventually take over in 1950 and in April 1964 he struck a deal with Toyota to open the first dealership in Idaho. Then, in 1984 and fresh out of college, Mark Peterson came on as the Manager of the Jeep store. With Marvin's experience and Mark's fresh ideas and customer focus, Peterson outgrew their location on 12th and Main and moved to the current location on Fairview and Maple Grove.

Now five generations strong--with Mark's sons Brady and Nils joining the team--Peterson Auto Group is Idaho's largest Car Dealership chain and is privately owned and operated. We live in the community where the dealerships are located and are in the stores on a day-to-day basis. This allows family values and relationships to permeate the businesses and create a real family atmosphere for our employees and our customers. Peterson views a car sale as the beginning of a relationship and a welcome into the family. Over the years, many of our clients are 3rd and 4th generation customers and have bought and serviced multiple cars with us. Our History and commitment to longevity, maintaining a safe and secure environment, with a relentless focus on customer service and our attention to the community are what's built the Peterson brand over the last 90 years.
