Holz Motors has grown from first year sales of just seven motorcars in 1914 to more than 5,000 new and used vehicles delivered annually. Holz Motors is the oldest Chevrolet agency in Wisconsin. It is possibly the oldest dealership in the state owned by its founding family. While Holz Motors operates from a modern facility with a large inventory and showroom, its record-breaking sales rely more on the company s homespun philosophies and traditional customer-driven practices than on anything else.
