Former Formula 1 ringmaster Bernie Ecclestone will be putting his racing car collection up for sale—a set that is estimated to be worth "hundreds of millions."

Amassed by the F1 supremo himself over half a century, Ecclestone's secret stash features race cars once driven by the likes of Ascari, Moss, Lauda, Piquet, Senna, and Schumacher.

The collection—reportedly worth about $400 million—includes the first Ferrari to win an F1 race and other iconic machines.
