Unlike some of the vehicles Leno shows off, this one doesn't belong to him. Instead, veteran Italian car mechanic Franco Barbuscia owns it. He has been maintaining Jay's Countach for years. A '91 Diablo is an archaic supercar by today's standards. It doesn't have power steering, anti-lock brakes or obviously anything like traction control. It's just a big V12 hanging behind the driver with a wonderfully meaty roar that emanates from the exhaust.
Franco's Diablo might actually be better than new. It has a few upgrades to aid in drivability, like re-spaced pedals, a carbon-Kevlar clutch and more. Apparently all of the tweaks help a lot because, "it rides smoother than my Carrera GT," Leno enthuses about the car.
