Helmut Marko
Horner moved up to Formula 3000 in 1997, founding the Arden team. According to Horner he set the team up with borrowed money, including a loan from his father, and persuaded P1 Motorsport founder Roly Vincini to take on the role of his race engineer. He bought a second-hand trailer for the team from Helmut Marko, who as head of the Red Bull Junior Team was one of Horner's main rivals as a manager in F3000, and who he would later work closely with at Red Bull.
