0$ over and above his base salary, which is not likely to be as much as Juans' current rate, I suspect.
Ralf sure painted himself into a corner with this one, with help from Willi, of course. Have you ever noticed that whenever there's a TV shot of Willi on race weekend, he's hangin' in the Ferrari pit? Can't blame him, really. It's like blue collar versus the upper crust. Or maybe Frank and Patrick won't allow him in the garage?
