Helmut Marko
He moved up to the European Formula Three Championship in 1979, driving a Martini with support from Renault, and switched to Formula Two in 1980 with a two-year-old March. On his Formula Two debut, Gartner's car was damaged by debris from the accident that killed his countryman Markus Höttinger. He was subsequently invited to take Höttinger's place in the BMW M1 Procar Championship series, in which he raced against Formula One drivers, driving for fellow Austrian Helmut Marko.
