How much do you need to tell your mates that you know what's what when it comes to your mobile stuff? The latest and greatest smartphone? An in depth knowledge of Apple's iOS 4, or just a numberplate on your motor to show them who's the top dog.
That's what businessman Jim Denoon has done for the last 7 years, but it seems hard times might be on Mr Denoon, and he is selling the plate for £20,000.
According to Mobile Marketing Magazine, of which Denoon is a reader, it has been on a number of cars he has owned since, including an Audi S4 that won the Cannonball Europe race in 2005.
Those interested should contact Jim directly - email@example.com.
