Juan Pablo Montoya to join Penske in the INDY Car series full time with a third car teammates to Helio and Will Power. The article doesn't say anything about Juan bringing money or sponsorship. This reminds me of the whole Stewart-Haas/Newman/Kurt Busch ordeal. Stewart/Haas tells Newman no money or room for you at Stewart/Haas, and then Gene Haas turns arounds and signs Busch to a mutli year contract, and says if sponsor can't be found I'll pay for it out of my own pocket.
Penske tells Ryan Briscoe and A.J. Allmendinger he can't run a thrid team without money or a sponsor, and turns around and hires Juan Pablo for his third team.
