This month’s sixth annual Muscle Cars party at the Mansion revved up auto enthusiasts, painted models, go-go dancers and many a partying Bunny. Hosted by Playboy Cyber Girl Melissa Dawn Taylor, the event gave guests the excuse to party with a purpose—50 percent of donations went to the It’s All About the Kids foundation. Rockabilly Band kept the music going on Hef’s front lawn while guests mingled with the 28 classic collectors cars and 10 vintage Harleys. Watch our video to see what happens when car buffs and cottontails come together, all in the name of rebel rides and a damn good party.
