About Walter’s Mercedes-Benz of Riverside

Walter’s Mercedes-Benz of Riverside is a true story of achieving the American dream. Owner and Founder Walter Kienle was born in Germany to Swiss parents and immigrated to the US in 1948. Walter quickly found work as an automotive mechanic, but elected to sign up for the Army in order to serve his adopted country. He went to tank school and achieved the rank of Staff Sergeant. While stationed in Riverside, Walter discovered how much he loved California.

Bringing German Heritage to California Sunshine

After an honorable discharge, Walter went back to New York to start a family and opened his own garage. Missing the warmer weather, his family moved to Riverside, CA in 1960. He started an automotive repair business specializing in European models, and in 1965 earned the right to begin selling them as well.

Walter’s Mercedes-Benz of Riverside has since expanded to become the Walter’s Automotive Group which includes Porsche Riverside, Walter’s Audi Riverside and Audi Ontario becoming the # 1 seller of European luxury imports in Southern California*. The Mercedes-Benz Sprinter center is now one of the top retail sellers of commercial vehicles in the country and will be opening a brand new sales and service center right here in Riverside, in late 2020.

Mercedes-Benz was the first and remains the largest member of the Walter’s Automotive Group. Walter sadly passed in December 2017 and now his son Steve will proudly carry on his Dad’s legacy. Walter would be proud to know his Mercedes-Benz store was recognized as a Best of the Best Gold Laurel recipient for 2018, which is the highest and most prestigious award a Mercedes-Benz dealer can receive. In addition to being a Best of the Best Gold Laurel, Walter’s Mercedes-Benz of Riverside was ranked by DealerRater.com as the Highest rated Mercedes-Benz Dealer in California for 2015, 2016, 2017, 2018,2019 and 2020.
