While Toto has done some amateur racing more recently, his single-seater career came to an abrupt end because of one factor: money.
Well, that and experiencing the talents of some familiar names up close...
"I think I got myself to the point where I was able to fight for wins in Formula Ford, and back then the German Formula Ford Championship was like the current Formula 4 or Formula Renault Eurocup, it was quite a strong Championship," he said.
"But I ran out of money. A sponsor stopped financing after the Senna and Wendlinger incidents in 1994, and this is why I stopped all my racing activities.
"Also, because I saw some of the young guys coming up who clearly had more background and a lot of talent.
"Alex Wurz is somebody who I have mentioned in the past but also Nick Heidfeld. He had just started his racing when it was my last year in Formula Ford. You could immediately see these kids were different.
"They were just faster straight from the get-go, even in their rookie seasons. I remember Nick Heidfeld was running a Formula Ford 1600 in a field of 1800s.
"The best 1600 would qualify midfield at best and we had rain and a wet qualifying in Zolder and this tiny little boy, I don't know how old he was, put his 1600 in the second row. You could see there were some who were more special."
