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."

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

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.
