Helmut Marko blocked Max Verstappen from taking part in a fan event which will mark Sebastian Vettel's first run in a Formula 1 car since his retirement.
The German retired at the end of last season after two years with Aston Martin. He raced for Ferrari before that, but the bulk of his F1 success came as a Red Bull driver.
Vettel will be reunited with one of his four title-winning cars later this year at an event at the Nurburgring. He will drive the RB7 in a show run for fans at the famous Germany circuit, and won't be the only F1 alum doing so.
