Bugger buying places, everything I have will be purpose built. Massive plot of land with workshops, garages, seperate log cabin for guests, cinema room, automagic gates, and a fully automated home. Would continue with my business, but could sink a lot of money into it, and employ people who actually know what they are doing!
I would spread a lot of wealth around, get OcUK to build half a dozen top end systems for people on here to win as prizes (say one a month).
And a nice Aston Martin for myself, that would be first on the list!
As for foreign homes, wouldn't bother. Would just stop in the best hotels. Possibly get a place on The World.
