VAG wouldn't fund a Lambo Team; they wouldn't stand to gain as much from it, financially. They'd be better off with Audi or VW - or even funding an Auto Union team (which, by the by, is what I'd like to see I think!)
Also, I'd like Colin Chapman's zombie to come back and start a proper Lotus F1 team... It'd be great, all about brains. Just like the good ol' days... Though maybe more about everyone else's brain and less about Colin's.
