Toyota are no. 1 for finance, Ferrari no 2, BMW 3 and I think McLaren are 4th? (or are they other way round with BMW)
Though then again you also have Red Bull and Renault around 6 and 5 I think
Is that in terms of what the parent company has as assets or something??
When it comes to who spends what in F1, I'm sure Ferrari and MacLaren are pretty much spending way more then most!
