The worst experience with it was tearing down the A3 one day. Suddenly I felt this incredible draught and wondered where it was coming from. I looked down and all I could see was tarmac. The whole driver's-side floor pan in front of my seat had just rusted away and dropped on to the A3 as I was doing 70mph.
Never mind the rust, the worst thing about the little Spit was that it kept on overheating. I spent a fortune on new radiators, hoses and pipes, but nothing seemed to cure it. I would still come to an unscheduled stop shrouded in steam. Then one day a friend said to me: "Henry, if I was you I'd reposition your numberplate." He was right, because the plate was bolted right over the air intake. I moved it and never had another overheating problem.
Sadly, that didn't make it a better car, so the Spit got cubed. The next disastrous car was a Range Rover finished in Surrey Green: a top of the range Vogue SE.
I found it fantastically fast and opened the bonnet one day for a closer look. Nestling on top was a silver box, which turned out to be a supercharger. The electrics were always a pain. One day after using it as a camera car in Liverpool, the driver's seat stuck in the forward position. Being electric, once seized, it couldn't be shifted, so I had a three- hour night-time drive back to London wedged right up against the windscreen like a little old lady.
The Range Rover had loads of warning lights that flashed all the time. I got so fed up and found them such a distraction that I put black gaffer tape over them. Maybe I should have paid a bit more attention to them because pulling away from the lights one day the supercharger went bang. It made a terrible mess and because it was welded to the engine rather than simply bolted on, cost a fortune to sort out. I originally paid pounds 22,000 and ended up feeling lucky to get pounds 6,000 for it three years later.
