Not sure if this is how it would work, but this is all theoretical anyway.
1.I'd pay off my loans, my parent's loans, and my sister's loans.
2. I'd get tint for my Jetta, refinish the wheels, get it repainted in the factory color, and buy some floormats. I'd then buy a lightly used sports car, likely a Porsche 911.
3. I'd buy a nice, small house with a 2 car garage and a big yard. I'd buy the necessary grounds-keeping tools as well.
4. I'd likely have a few hundred thousand left over if I found the right house, so I'd invest some, donate some, and party with some.
