Not bad west... not bad.
Personally, I would invest 900,000 then i'd get a nice ride... i dunno what, but something for the mountains... an SUV probably (i know everyone thinks they suck) then i'd go to school and get my buisness degree.  When i got i'd get a sports car... E36 M3, or an M Coupe or sumthin... once secure with a job i'd get a pimpin flat in Downtown Van City, and a decent log cabin at whis... something nice, but not all close to the town center and shit... further out (cheaper, more usable, quieter, and better for house parties) if i ever needed to get home when drunk or anything, I'd be a fricken millionair so i'd have a taxi on standby.
Oh, and to Five-0's comment on as soon as you spent a dollar you woulndn't be a millionair... thats not true, cuz i hope you wouldn't be flat broke when you got this million, and other than food and things without value... you can put your money in assets.  ie. furniture, home, art, stock market, jewlery, whatever.
if you had 400,000 in the bank and owned a 600,000 house with no mortgage then your a  millionair.
