And for the Japanese fans there is also Super Aguri... is somebody going to buy the team??
Let's see the manufactures that are capable of starting a team in F1:
1 - VW or Audi or Bugatti or Lamborghini (same group)

2 - Citroen or Peugeot - PSA Group is now the secound biggest manufacturer in Europe and they have to compete with renault!

3 - Hyundai - super rich group that could easily spend as much money as a small country in F1

4 - Lancia - Belongs to FIAT... Ferrari
5 - Nissan

6 - Subaru - kind of owned by Toyota
OBS - None american manufactures in the list cause amercians are all eyes for nascar... well... if thats real racing...
Anyway there is only room for two new teams and a slot from late Aguri and there is the Toro Rosso issue... wich would I guess:
Toro Rosso - Lancia
xxxxxxxxxxx - Porsche
Super Aguri - Peugeot
xxxxxxxxxxx - VW or Audi or Bugatti or Lambo!!

OBS: I'm a F1 fan and as so I would love to see many teams but not just car manufacture's teams... but we have to be realistics.
sorry for my bad english. I am from Brazil.
