London is full of these typed of expensive cars, for examples, a
mercedes mclarren and lots of bugatti's and paganni zonda and
lamborghini's !!

I want to know what do these people work in London?

They probably work in financial services - London is the largest
financial centre in the world and huge salaries and bonuses are still
being paid out, despite the global downturn that affects ordinary
mortals.
