This summer Royal Purple sponsored the Second Annual Show it Off at SEMA Contest. Up for grabs, two vehicles would be invited to display as Feature Vehicles as guests of Royal Purple at The SEMA Show at the Las Vegas Convention Center Oct. 30 – Nov. 2. After a round of online voting to select the top ten vehicles, all finalists were asked to submit additional photos and spec sheets to a panel of judges who would determine the two winners.

One of the winners was Dennis Rostenbach‘s 1970 Custom Road Runner.
