It started with a wrench and a dream back in 1923. LG Peterson was fresh out of the Army where he served the Ambulance Core as a driver and mechanic during WWI. The Military had recently deployed motorized ambulances to replace horse-drawn carriages and LG had a knack for fixing them.
About Us
We are a family-owned-and-operated dealership, serving Idaho drivers for over 100 years

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.


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. Many of our clients are 3rd and 4th generation customers who have bought and serviced multiple cars with us.
