That's not all....
He has, or has had, a black Ferrari FXX, Ferrari 550 Maranello, Ferrari F355, and some 430 Scuderias, which he had input on the design of, and is nuts about Harleys, and also owns superbikes, and occassionally tracks them. He often goes to the American Midwest on vacation and rides Harleys for uninterrupted miles, something you can't do in Europe very easily. He has racing go karts which he uses to keep his reflexes sharp, and many many other vehicles. It's never mentioned but I'd wager he probably owns a few German cars too, being a native German, that combined with the fact that he is being lured to return to F1 by Mercedes recently. To even imply that he has a Chroma and an Abarth sitting in his garage and drives nothing else, might be a tad of an understatement. Fiat will get him to drive anything they can so they can film it or get the press to see him driving it, and make it look like he owns one.
In 2008 he was driving a Fiat Scudo van in Kent England and hit a garage door that was sticking out into the road. He also did a commercial for Fiat for the Scudo....
