He earns enough to buy one easily, however the problem is not affording one, but finding one - there are only 100 (...ish - some are NEVER for sale like the one in the McLaren Garage), and while they were £640,000 new, the used price is easily in excess of £1m...
Off Topic - That LM isn't the one he'd get - that one was at the London Motor Show in 2006 (would dig up a pic if i could find my way around my own bloody website).
Still an utterly crazy car though - my fave car of all time, and all for that beautiful engine note!
