With a gazillion color options for every little part of the Bugatti Veyron, there's no reason why any two examples should be alike. (Except for maybe an inverse correlation between wealth and imagination.) So it would stand to reason that every Bugatti should be considered a special edition of one. And that certainly appears to be the case, as the French marque seems to bring out another special edition at every possible opportunity.
