At what point does a conspicuous display of wealth become obscene?

Well, a solid gold, diamond-encrusted model of a Bugatti Veyron, if it doesn't cross the line, certain comes close.

It is called, officially, the Bugatti Veyron Diamond Limited Edition and it's a scaled replica of a true Veyron (1:18) in solid 24-carat gold, platinum and adorned with 7.2 carat single cut flawless diamonds.

The model is a creation of Munich-based Robert Gulpen and Stuart Hughes from Liverpool (UK), both known and respected figures in the world of bespoke luxury design.

The doors and hoods are functional, meaning they open and close, and the steering works too.

Only 3 will be made.

Cost/Value? £2 million (€2.4 million).
