If you are looking to make some extra cash, there are lots of ways to use your car as an income source — with or without you behind the wheel. Here are five ways to make money with your car with relatively little risk. Drive to the airport for a trip and park your car in a lot owned by FlightCar. You get free parking and a free car wash. The amount you earn depends on your daily commute and the size of your car which directly translates to the amount of advertising space. With companies such as Uber, Lyft and Sidecar, you can get paid for it. These services allow you to set your own schedule for offering rides. If you are able to find riders for your regular routes, however, that is extra money for driving somewhere you are already going. Register with a company like RelayRides and customers will rent your car, picking it up from a location you designate including your home or your office and return it to you. You may also like.
