Excuse me butting in on this thread, but I think that the money owed by Minardi is a red herring. Minardi was always pretty much a plaything, and it has no real assets, so any talk of the loan being repaid is fantasy. The cars are curios, and totally uncompetative and worth essentially nothing, the drivers contracts are worth even less, most of Minardis drivers have paid to drive the cars, they are not that good. If the whole team was wound up it might just realise $1,000,000. The only thing of value Minardi has is the right to race in Grand Prix.
Just had a thought though, F1 requires you to put a deposit of several million in some sort of escrow, to ensure that you race the whole season, could the £6 million be that? In which case the money will only become available at the end of the F1 season (september ish) provided that you have entered all races.
Bottom line, forget about Minardi money, if its going to come into the company, it will come by the time you have, hopefully, got another job.
