SteveP that aint a bad little street for spotting cars. And I now know what you meant when you said "I work in a corner shop in Knightsbridge" ha ha!
Just to put my two cents in, I work for an investment bank near St Pauls in London. And normally parked just outside my window is a Lambo, and in our under ground car park, the head of the Global Markets traders parks his Lambo LP640, or his Bently continental GT. On contrast to that the CEO (this guys boss) parks her Fiat 500 (the Abarth version mind

) there too. Quite funny seeing that parked next to a massive Lambo. I have also seen a BMW M6 and a DB9 parked down there too, no idea whos they are though, must be some of the stupidly rich traders? Bastards ha ha!
Makes my MK5 seam cheap in comparison.
