Horter Chev Pontiac is a small, long-established General Motors dealership based in Mukwonago, Wisconsin. Founded in 1928, it is recognized as one of the oldest GM dealerships in Waukesha County. The business originated under Archie Koeffler, later taken over by Harold Koeffler, and Tom Horter joined in 1979 as sales manager before becoming dealer principal in 1986; in the early 1990s, the Pontiac franchise was added and housed at the current site alongside the Chevrolet operation. The dealership represents Chevrolet and Pontiac and serves local buyers seeking General Motors vehicles. Its long-standing presence in the region reflects its role as a local automotive retailer within the motor vehicle manufacturing industry.
