Businessman Afzal Kahn received an offer of £6 million for his registration plate, and he turned it down.
Kahn bought the plate in 2008 for a not inconsiderable £440,625 and put it on his Bugatti Veyron.
And while it might sound like silly money, it was clearly a worthwhile investment, because even during the credit crunch years, it appears to have increased its value almost 13 times over in half a decade.
Kahn believes that the plate is worth more than he was offered.
A spokesman said in quotes picked up by the Daily Mail: We have received a significant multi-million pound offer for the F1 plate which we rejected out of hand. Mr Khan has no interest in selling F1, which is his favourite plate. It really shouldn't be a shock to people that the number plate is worth millions of pounds.
