I can only think of vettel, webber, button, kimi, hamilton that didnt bring money into the party to themselves a drive.
But hamilton/button did do a lot with santander and button still does but I assume button didnt really bring them on board as such.
Its a shame about hulk, he gets booted out of williams because maldando brings aload of cash, spends a year sitting on the side lines hoping for a seat, gets one and ferrari give him the nod, so he moved to sauber so that ferrari could assess him for a year to prove he was good enough for the team, only to get beaten to it by kimi.
Realises thats all gone wrong, mclaren wont have him because hes to heavy and lotus need money so they are getting maldando(so thats twice the venezuelan has screwed him)
So looks like hes back where he started at force india, unless he starts putting the car on pole every weekend and his team mate is last I dont know what else he can do to prove his talent is better financially(higher up the constructures) than bringing in a sponsor
