About Us


Born in Germany to Swiss parents, Walter Kienle trained as a tool and die maker until he immigrated to the U.S. from Switzerland in 1948. Here, he worked as an automotive mechanic in Redding, PA until he felt compelled to join the U.S. Army to serve his new country.

Stationed at Fort Irwin in Barstow, Walter quickly earned his stripes as the top student in tank school and was quickly promoted to Staff Sergeant. As a non-commissioned officer (NCO) he earned privileges at the March Air Force Base NCO Club in Riverside, CA where he was first introduced to the mild weather and friendly charm of Southern California.

Upon his Sergeant First Class discharge, Walter moved back to New York where he opened an automotive garage, married and started his family. Longing for that California sunshine, he returned to Riverside in 1960 and opened Walter's Automotive Service with an emphasis on European makes.

Based on his excellent reputation for service and technical skill, Mr. Kienle opened Walter's Automotive Mercedes-Benz Service Center in 1964 and became an authorized selling dealer in 1965.

Porsche asked Walter's to become an authorized dealer in 1992 where it now enjoys the status of being one of the top Porsche dealers in the U.S. In 2004 the Audi line was added as a natural extension of Walter's fine line of German automobiles. Over the past 40 years, Walter's has expanded eleven times to become the multi-location auto group it is today.

Walter's son, Steve Kienle joined the family business in 1979 and now serves as General Manager for all three dealerships. Steve and his wife Cathy proudly reside in the Inland Empire and have greatly expanded Walter's contributions to the community. The annual Walter's Children Charity Golf Tournament is a tremendous success and has contributed nearly $2.6 million dollars to the Loma Linda University Children's Hospital.
