Auto Motors of Lehigh Valley started in 1992 by Charles Terry Kozo as just engine and transmission replacement, committed to installing high-quality replacement powertrain units to extend the lifespan of cars and trucks. Stephen Lang Jr. joined the shop in 1994 when his father retired and sold their business, Lang’s Gulf, and brought diagnostic work and general repair to Auto Motors of Lehigh Valley. Steve bought the business in 2011, with his son Derek J Lang joining the company in 2012 to manage the office. In April 2017, Derek bought the business from Steve to continue both his and Charlie’s traditions of quality and honest auto repair work. After having incorporated Diamond Automotive into our family as of April 2017, we now operate with 4 full-time technicians and 7 bays.
