Maybe I have too much time on my hands. So for reasons that I’ll probably explain in the magazine at some point, I put a Banksy on my bonnet.

It is amazing what you can do with a spare can of white enamel spray paint, a bit of cardboard, some scissors and some sticky tape. I thought it might go badly wrong, but I didn’t have much to lose considering the state of the bonnet in the first place.

Painting and decorating your car is a wonderfully childish and, it has to be said, liberating thing to do. I mean why do I want to rely on the Adam and Mini marketing departments for funky colour combinations? Provided I don’t need to worry about the resale value, I might as well do what I want all over my motor.

Indeed, the bravest thing I have seen was an old Porsche 911 that had been painted in the style of Piet Mondrian. If you know your artists of the De Stijl movement, you’ll know just how wonderful that would look, all coloured rectangles over Stuttgart’s greatest hits.

So expressing yourself over a car doesn’t mean it has to be a worthless piece of kit like mine to get away with it. Many years ago when Renault Espaces were quite square things, a photographer I worked with had let his children paint the doors.
