I think Ferdinand Porsche is credited for that one. Anyway, it's a very old saying. That wasn't accurate in modern Formula 1, especially when Paul Stoddard decided to buy Minardi. To quote him, he 'invested because it was booming business'. I wouldn't deny that he loves the sport, this is extremely accurate. But he didn't buy Minardi because he wanted to rescue them; he bought it because it was cheap and he really though he'll get a large fortune.
