Indy car drivers and NASCAR drivers have long had to bring sponsorship money with them. Bobby Allison was a fantastic driver but equally important, his Coke sponsorship went wherever he did. Indy car drivers were in the same boat, no room for talented newcomers if they didn't come with a ready made sponsorship deal.
Things aren't always how they appear to be! There are more people that can drive a car well than seats to fill so teams can be pretty picky and driving ability alone doesn't get a ride.

I was watching some show about racing and they spoke of an American team- 60s? 70s?- That went to lemans to compete and did well.
They had a disagreement with their team about driving order and decided the fix was to buy the car. The team owner threw out a crazy number, to shut them down and they handed over cash and solved the driving order problem real fast-like.
Turned out the brothers were dealing drugs for money...had hidden NOS in the car and were all kinds of crooked.
Whaddya know about that?!
