A friend of mine caught a pic of these two Bugatti Veyrons during a holiday to the south of france (Monaco F1/Cannes film festival combo). The first one seems to look like the original:

The second one however looks weird. There are parts from the Noir Sang limited edition (wheels, headlamps), but not all of them? Also he (my friend) claims that the second Veyron seemed smaller than the first one - So maybe it's a kit??
