...and now Marussia is in administration as well. Unless additional investors show up, both will likely close their doors at the end of the season.
Bagwan makes a good point, though. With Caterham not showing up, what's the benefit of Marussia spending the money to go? Based on Bernie's remarks last week, I don't think there's a penalty for them in not participating for two races, so there's no benefit to them in terms of standing by showing up.
