I was digging through some old pictures yesterday and found this from the FOS in '95 myself next to JC. Clarkson was hungover and driving the purple Diablo up the hill. His head stuck out of the top....
I don't know if he still goes. As you can tell this was a few years back before Top Gear was as mainstream as it is today. He may get mobbed if he were to go now. Back then a lot of people didn't even really seem to recognise him.
