Throughout the 1980s and early 1990s, Miller acquired a number of automobile dealerships in Utah, Colorado, Arizona, and New Mexico, creating the Larry H. Miller Automotive Group. In 2007, Selling Power listed him as the tenth-largest U.S. automotive dealer, with 42 dealerships and sales of $13.5 million. Miller placed a strong emphasis on vertical integration to help his car business. For example, he started an advertising agency, a printing shop, and an insurance company. By the 1990s, Miller's reputation made financing new business ventures much easier.
