Pay off my car
Setup college funds for my nieces and nephew
Talk to my financial advisor about how to turn the remainder into more money so I can retire, and travel.
I was going to say, no way in heck i'd buy that with only 2 million, even it was enough I wouldn't want to take out personal loans for oil changes (you can't do your own on a veyron), house mortgage for tires, and then resort to crime when a brake job comes up.
I'd start with a 2004 5spd Forester XT, have my mechanic friend build the engine for me so it's reliable and plenty fast, then do all the other fun stuff myself.
Get a nice 1/5 scale RC
edit: I figured the "sensible" things go against the point of the game, but yes, those would have to come first.
