In 2015, the O'Reilly Shredder car was purchased and introduced as a show car, initially displayed on a circuit around the U.S.A. when O'Reilly Team Members took it to Grand Openings, events, and more. A few years later, it was brought to Springfield, Missouri, where it has been featured and used at select events, including NASCAR races, the O’Reilly Leadership Conference, and other notable occasions. At the 2023 O’Reilly Leadership Conference, the car’s new wrap was unveiled, and a contest was held to determine its new name—the Shamrocket. Today, we continue to use it as part of our activation display at various national motorsports events.
