Porsche Ontario is one of the newest Porsche dealers in Southern California. As part of the Walter’s Automotive Group, it continues to provide the award-winning customer service. The Walter Automotive Group has a long-standing history of excellent customer service, but it all has stemmed from the year 1948, when Walter Kienle emigrated to the U.S. from Switzerland. After several years working as an auto mechanic, serving in the U.S. Army, and opening and managing an automotive garage, Walter eventually settled in Riverside in 1960, where he established Walter’s Automotive Service with an emphasis on European cars.
