I met Biz Stone today – the co-founder of Twitter. He was in London to give a talk and after interviewing him on the telephone last month, I couldn’t resist saying ‘hi’.

Biz is worth quite a lot of money but he’s a pretty down to earth guy. He drives to work across the Golden Gate Bridge in San Francisco in a VW Golf when, in fact, his shares in Twitter could buy the bridge. And every car on it several times over.

Flash cars aren’t his thing. I can understand that but after a lifetime testing cars, I think that if I was Biz, a Boxster S would be a ‘modest’ drive for billionaire me.

it would be the benchmark sports car. Not too ‘in-her-face’ and, in London, they’re two-a-penny anyway. Forget comments about this being a hairdresser’s car – the Porsche is an exceptional driver’s car and not to be sniffed at.

Last week I asked the question, is the Boxster S worth the price of four Mazda MX-5s…. The answer, quite simply, is yes.
