My own arbitrary (and not necessarily straight) line in the sand:
There are owners who started racing, learned about running a team in the lower ranks, built upon their own successes, and finally got into F1.
Then there are owners who let other people do all of that, and bought them out.
Red Bull : Bought Paul Stewarts hard work
Toro Rosso: Bought Giancarlo Minardi's hard work
Force India: Bought Eddie Jordan's hard work
Mercedes: Bought Ken Tyrell's hard work
Marussia: Bought John Manor's hard work
Lotus: Bought Ted Toleman's hard work
Caterham: Bought Litespeed's hard work
I'm not saying that the second group doesn't love racing, but I have no love for those teams.
I don't think those are all exactly correct.
For a start, the team Mercedes brought was founded by BAR - Tyrell had nothing to do with them except the paperwork. Marussia were involved with setting up the team right from the start, and John Booth is still the team principal (was there a John Manor?). Caterham had nothing to do with Litespeed F1 effort. Fernandes brought in Gascoyne to set up a team from scratch once the Litespeed team was declined entry.
