Miller had a much more positive experience Chuck Stevinson Toyota in Lakewood, Colorado. In 1971, he was hired to turnaround their parts department. By his second year on the job, it had the highest parts sales of any Toyota dealership in the United States. Miller achieved this by building a national wholesale business instead of just focusing on the local market. Miller took advantage of the demand for locking gas caps during the energy crisis by buying the entire wholesale stock of such caps, which were only made by two companies. In 1973, Gene Osborne, part owner of the dealership, offered Miller a promotion to general manager. This promotion did not take effect until 1974 due to the oil embargo of the same year. In 1977, Miller was appointed the operations manager for all five of Stevinson's Toyota locations. Miller was eventually demoted to head one of the locations in order to make room for Stevinson's sons, with Miller asked to mentor them. Miller's work with Stevinson gave him national recognition among Toyota dealers and repair shops.
