Winning that curious anomaly, the Swiss F3 championship, in 1986 in a Dallara meant little, and the wealthy Foitek's first season in F3000 the following year was to be a more searching test. A poor start and a string of DNQs were to some extent overcome by switching teams to GA Motorsport in mid-season, though it was 1988 before he tasted success with a superb win at Vallelunga. But then came a worrying number of incidents, culminating in the Johnny Herbert crash at Brands Hatch, when Gregor's Lola was launched into a terrifying series of barrel-rolls from which he was fortunate to escape with no more than a fractured wrist. Moving into Grands Prix in 1989, he spent a fruitless time trying in vain to qualify the EuroBrun, and decided to quit while ahead when the rear wing fell off on his debut for Rial. Foitek took his money to Brabham at the start of 1990 and at least made a couple starts, but then he moved to the Onyx team, which was on the way to oblivion as a Swiss gentleman by the name of Monteverdi took control. All in all, it was a sorry mess and before long Foitek had disappeared from view.
