The guy does have some seroius money to spend. He owns a real P4 ( or a bitsa special, take your pick) as well as a GT40, and who know what else.
Good luck to him if he can make it happen. The first hybrid Ferrari to race at Le Mans. The cynic in me is put in mind of the Ferrari indycar that was wheeled out everytime Enzo wanted a rule changed in F1.
A Ferrari P1 customer car would be popular, and a good sell to sponsors.
