Hmm, I think I can do this in quick order...
Pay off house - 250k
RS6 Avant (hell yea, Phil!) - 125k base + import/emission/crash taxes/fees so lets say 150k total? Toss in Audicare too
Porsche Cayman R - 90k
Pay off current S4 - 30k
Do lots of fast things to current S4 - 20k
Figure out if the fast S4 is faster than the RS6 - 20$ (hey, gotta find a drag strip)
Flip the house and move up closer to Beaver Creek (thinking Arrowhead), drop 400k on a down payment + money out of house
New "demo" quiver, grabbing a bunch of the latest skis and bindings for next season, toss in some new ski cloths too - 10k
Got 50k left.... fly to South America 1st class for some southern hemisphere skiing.
Anything left over, pick up some high end tech, Macbook pro, Thunderbolt display (2x), 4k TV, next gen consoles etc etc... maybe some new furnishings for the new place.
And still anything left over, one hell of an expensive dinner and lots of booze
Man, that 1 mil went fast
