Perhaps Johnson's most prized possession is a 2006 Chevrolet Monte Carlo, the car that propelled him to his first of five consecutive Sprint Cup championships. "I have a number of cars from 2006, but this is the one I drove during the final race at Homestead." This one-of-a-kind ride was enough to make Johnson beef up his security. "We've got all the bells and whistles, from video cameras to alarm systems," he says. But sometimes it takes a village. "There's a close eye on the warehouse, not to mention the friends I've made on the police force who sit in the parking lot."
