Gerhard Berger has for now ruled out returning to the F1 pitlane as a team owner.
After retiring as a veteran driver and winner of ten grands prix in 1997, the Austrian served as BMW's joint motor sport director until 2003.
He came back to the pitwall once again in 2006, having bought half of Toro Rosso from his friend Dietrich Mateschitz, but he sold the share back to Red Bull at the end of 2008.
Asked if he is considering a return to team ownership any time soon, 51-year-old said: "With the conditions in Formula One today, there is not the opportunity.
"I can't afford it," Berger told Germany's Auto Motor und Sport.
"The sport has become too expensive and you can't find the money that you need to do a good job on the open market."
