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 have been waiting to win a world championship since 1985. I've had three cracks at a world title - in karting, I finished third at Le Mans; that hurt because it was very close, but then in Formula One there wasn't really an opportunity to finally crack it, so it's third time lucky.

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.

I clipped a Ferrari, hit the gravel trap at a fair old speed, which lifted the car up into the barrier, and then rolled a few times. I had no injuries or anything - I just had to wait for the marshals to right the car before I could get out.

I think music can really affect people's emotions and, when I am about to get into a race car, I definitely listen to music with a good beat - that's when you've got the adrenalin pumping. And the time before you go into a race weekend, you have a lot of emotion and adrenalin, and a lot of focus.

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