One of the best cars I have driven is the Alfa Romeo 155 V-6 Ti which I used to compete in the Deutsche Tourenwagen-Meisterschaft and International Touring Car race series in the 1990s. I drove for the TV Spielfilm and the Jas racing teams. It gave me victories, pole positions, fastest laps and things like that. However, I must qualify things here, I consider a car such as this a car that can be raced, but not a racing car. To me a racing car is just that, a car specifically designed to race, not adapted to race. So please forget touring cars as being racing cars!
In Formula One the Zakspeed cars were quite an experience, not very good cars, not so slow though. They did the best with the facilities and budget they had available. Unfortunately, I did not score any world championship points with them, but it did give me a foot into the world of Formula One, where I also drove for Osella, Arrows, and Rial.
