Okay, so you loaded up on stocks and were making a killing and decided that you should spend this endless stream of money on an Aston Martin. That's a great idea, right? The market plummets; the economy takes a dump and your stuck with a $1500/month car payment. You can try to sell the car but no one is buying gas guzzlers and especially not ones that cost as much as an Aston Martin. You could reduce the asking price but you probably owe way more than the current market price of the car. What do you do? Start using it to deliver pizzas. You better hope you deliver to some big tippers.
