Not all car-loving celebrities are like Jay Leno. While there are many famous people with extensive car collections, few actually drive their cars as much as Jay.

Adam Carolla isn't as enthusiastic about using cars like his 1968 Lamborghini Islero for their intended purpose. The vintage Lambo was fresh off a repaint and Jay decided to do Adam—and us—a favor and give it some exercise on Jay Leno's Garage.

The Islero comes from the era when Lamborghini was still making front-engined GT cars and—with just 125 made—it's likely much rarer than any of the subsequent mid-engined supercars Lambo is known for. It still has some features in common with those cars, though, like a V-12 engine and a name that honors a Spanish fighting bull.

The last time one of Adam Carolla's cars was on Jay Leno's Garage, it ran out of gas. There were no such problems this time; in fact Jay and Adam noted that the more sensibly-styled Islero is a lot easier to drive than most low-slung supercars. That V-12 sounds pretty fantastic, too.

Jay has been busy recently. He auctioned off his 2008 Dodge Challenger SRT8 for charity at the Gooding & Company auction in Scottsdale, Arizona, raising $565,625 for the USO. It's just one of the valuable muscle cars that crossed the block at the spate of Scottsdale auctions over the past week.
