In 1965, Chevrolet felt that the TUCSON market had grown large enough for two dealers and a second dealer was appointed. O'Rielly leased its old facilities at 415 N. 6th Avenue to the new dealer and moved its entire operation to the Park and 22nd street facilities, its third move, while it began designing and building its new "state of the art dealership" at 6100 East Broadway. This facility was completed in 1966, and O'Rielly relocated its entire operation to that location, its fourth move, with the exception of the satellite used car facility at 3313 E. Speedway. The new Broadway dealership had many unique features, including one acre of rooftop parking and a new diagnostic center. By the time the new dealership was completed in March 1966, the Park Mall development had begun and Sears had opened the previous fall.

In the spring of 1998, O'Rielly Chevrolet opened a satellite location on 22nd Street near Swan for commercial fleet customers. O'Rielly Motor Company and all of its subsidiary companies are an important asset to the TUCSON and Southern Arizona communities.Â
In 2010, General Motors recognized Buck O'Rielly for 50 years as a Chevrolet dealer, a tenure matched by very few in the industry. In that same year, Buck's son-in-law, Rob Draper, succeeded Buck as a Dealer Principal of O'Rielly.Â
In 2013, O'Rielly undertook a major remodel of its dealership on Broadway. While the nearly 50-year-old design was still incredibly modern, it was updated to include an expanded, more easily accessible new vehicle showroom, climate-controlled delivery facilities, an expanded Corvette Cafe, a new two-story used car sales building, a car wash, and other state-of-the-art improvements. The next year, in 2014, O'Rielly Chevrolet was recognized by General Motors as "Dealer of the Year". Â

In March of 2024, O'Rielly entered its 100th year in business. It remains the longest-running dealership, and the largest Chevrolet dealership in Southern Arizona, and is looking forward to celebrating its 100th anniversary on March 18, 2024.
