I gave my Tyrrell Ford from 1971 to my son Paul and I gave the last world championship car, the Tyrrell 006 to Mark, my younger son. And I have five or six Stewart Grand Prix cars still.

Probably, recently, the Porsche Carrera 4S.

No, it was one of a group of cars. I was involved in so many different ways with Ford. I was in R&D, developing vehicle dynamics, commercials came with the rest of the package.

I was scared of it to begin with, of what we had taken on. Everybody thought I'd lose my reputation because I'd lose my money and we couldn't do it. But we did it. The amount of homework I did, we had a first class CFO, good quality people. But when it came time to sell it, it was with enormous relief. I had intended…

He unquestionably has the best car with the best designer (probably) in the history of motorsport. That's because of Mateschitz funding a fantastic package.

No delays. Never as a racing driver was I not paid on time. And never at Stewart Grand Prix or Paul Stewart Racing were we never paying our bills. If you can't afford it, you don't buy it.

The Pinto was not a great success.

Never.

Well, I think Hulkenberg and Paul di Resta.

Yes.

Sounds like a good idea to me, but I've got two children and a wife of 51 years, and I have 9 grand kids. I can't afford another birthday.

I think the turbos are a shame, mainly because of the economy. It's hugely difficult to finance. What it will do is that the car will use half the fuel that the current cars use. F1 is taking notice of ecology, the governing body are eager to be greener.

One was the Armco barrier, second medical aid, because the chief medical officer at Brands Hatch was a gynecologist. I'm sure he was a good doctor and good at gynecology, but it wasn't the work that would be good in a racing accident.

By being spotted in the same was as baseball, basketball, etc. You have scouts that go out, and if they see someone come along that's outstanding, you get a chance to drive something higher up, then more scouts come along, then you got into support events.

He's certainly not the worst driver in the world. Funnily enough, I had wanted Jeremy to come on the show. I saw Jeremy on the track at Laguna Seca and I thought he needed some help, so I called him up and said we should do some driving together. He thought it was a great idea, but not with him.

What we have is built in to our cars and also regulates safety. Our fuel systems, for example, in my day there were consistent terrible fires in F1. Now there are no fires. The drive in my day was sitting on the fuel tank, that doesn't exist today. They're created in such a way that they won't explode in a heavy…

I think whether you're talking something as basic as the paddle shift or something like DRS, it's new tech use it to it's best advantage.

Technology moves along, you have to use it, KERS is delivering additional horsepower that you wouldn't have under the regulations, and it's given us passing. You could say it's falsifying the situation, but I see these things as positive.

I think the animal hasn't changed, the times and the cars have changed. There's only ever one outstanding person, it seems. Comparing eras are very different. All you can say is that they were the best of their time.

1969 Matra M80RA with a Ford engine. That was my favorite.
