Do you really want to say that Ferrari is the same as Toyota?
Ferrari, like Lotus in its day, builds road cars to support racing. with the other 5, racing is (was) basically an advert campaign.
Enzo Ferrari build and sold road cars to support racing. Fiat went along for a share of the profit.
Enzo's gone, Ferrari races in Formula One to sell road cars. It's a massive brand, I'm sure it turns a huge profit, which helps keep Fiat independant.
I'm sure there are plenty of people in the Ferrari organisation who believe that the entire operation builds to the F1 teams, but I doubt the people in charge look at it that way any more.
We saw earlier this year that Ferrari knows it is bigger than Formula One.
