Which was the four-wheel-drive twin-turbo Über-Porsche of its day, the late eighties / early nineties -- and probably still a credible threat to any Ultra-Ferrari F40, F50, or (upcoming) F60 on real roads.
I *think* I read somewhere, a few years later, that the model had been legalised for US road use, retroactively legalising Gates' car and that of whoever the other guy (Paul Allen, Steve Forbes?) was, who imported one at the same time as Bill.
But I'm not sure.
