I'd buy a cheap used SUV for cash (need something bigger to haul kids + girlfriend + dog when we get one), and invest the rest. I'd keep it liquid enough that if I needed it for a down payment on a house in a few years I'd have it available for that, since I had to sell the house in the divorce and currently rent.
But my big life goal right now is to pour as much income into savings/investments as I can stomach, to make up for the years of being married to a spendthrift who spent every dollar we had and more.
