It is hard to be number one, and it is even harder to stay there because everyone is trying to knock you off the top.

My very first car was a grey Alfa Romeo Alfasud, which I got in 1987. But, in our family, all cars were for sale - so they might be there in the morning and were gone at night. In the mid-90s, I joined Porsche and the Carrera was the car, and the Carrera 4S was the one they gave me. As a wee boy from Dumfries, I couldn't believe it.

It was not until I started racing for car manufacturers that I found a car I could really get attached to. I am the son of a car dealer, so up until then, cars just came and went.

I don't do much driving - about 5,000-6,000 miles a year. And most of that is to the airport and to the racing circuits.

What I like is when you can hear the heart and soul of music and can feel the energy coming out of it, because that's what it's like when you drive.

It is hard to be number one, and it is even harder to stay there because everyone is trying to knock you off the top.

I have been listening to sport and watching sport on the BBC since I was a tiny boy.
