According to bornrich ”Bugatti Veyron and its editions have forever made headlines around the world for being unique in some way or the other. Each of the 30 models produced so far have been sold out, and most of them have been uniquely redesigned for extra features, adding to their novelty value apart from already overpowering speed capabilities. We covered some editions such as the last production model sold to a European buyer, and also the Sang Blanc version which was given a special pearl finishing on the body. Extending the list is a Sang Noir version which is listed as the most expensive new car to be advertised and comes as being only the 2nd edition of the Super Sport model to be produced by the car maker”.
