In the short term, immediately buy the requisite super car (probably a Lambo and Ferrari), one for me and my son. Sure he's under age, but I can probably rent out a race track somewhere. Will also be able to actually contribute substantively to the Car Spotting thread.
Long term, sit on the board of a worthy charity or two, take care of my family and extended family, buy a 1000 acre ranch in Montana and Wyoming with a self-sustained big-ass house, send kids to the best schools, wake up to see the Rockies every morning. Ba-by NJ.
