First off, i'd get in touch with Mr Travolta and make him an offer on his house:

I would also do the usual, buy loads of cars, not just exotic, but the stuff i've always wanted to try. Pay off all my familys bills mortgages etc and set them up for life.
One thing I would do is put the wifes Audi 80 in to a proper restorers/tuners and spend a fortune putting the biggest most powerful diesel in it but leave it as close to stock looking as possible, she wouldn't mind, she'll have the brand new Range Rover and Audi A4 convertible to potter about in.
I would also ring all my debtors (and there are a few) and ask them the lowest amount they would accept, then try to beat them down, except Northern Rock, whom I shall pay in full, as they are the only human debtor out there, so far

Then I would get as far away as possible from this bloody awful country!
