Can't afford gas? Make your car a billboard!

With gas prices so high that it seems like it costs $40 just to get to the next gas station, alternatives must be considered. Rollerblades and bicycles aren't good for long distance commutes, and getting a horse might annoy the neighborhood association. One alternative: make your car into a billboard, and get paid hundreds of dollars to promote everything from insurance to energy drinks.

But according to a 2005 Bankrate article, the industry is rife with scams. Never work with a company that asks for an up-front fee, and be wary of big promises: no one is going to give you a car. Be realistic. Given high gas prices, there are a lot of people who would love to turn their cars into billboards, and your chances of getting picked are slim.

But it may be worth a try. One of the reputable companies in this field is FreeCar Media. Here's their pitch:

FreeCar is advertising supported. Advertisers choose the drivers they want based on the information you provide us. You will never have to pay a cent to participate in the program.

When you are chosen, your vehicle will be wrapped in an attractive advertisement and you will get paid up to $900 a month. Most programs average 3 months but some are longer and others shorter.
