Free Paint Job
You may not have control over the design, but if you park in the right location, you can indeed get a free paint job for your vehicle. This artistically-painted truck was parked in Chinatown in New York City (though I can't confirm that this is the artist's location of work). For this graffiti photo, I got down very low to the ground to capture a modestly-upward perspective.
