This particular car, an F2001 that, not surprisingly, was used during the 2001 F1 championship. It won two of the three races it participated in, and helped Schumacher win one of his 7 championships. It's in racing condition, and Ferrari will help with storage and transport for the car.
The car's sale isn't just about a rich person getting a fancy collectable or toy though. Sotheby's notes that an undetermined portion of the proceeds will go to Michael Schumacher's charity, Keep Fighting. Among the charity's causes are road safety and head safety. The latter isn't surprising considering Schumacher's unfortunate skiing accident in 2013 that left him with a traumatic brain injury.
