Turn Your Company Car Into a Marketing Campaign on Wheels A look at three companies who are using their cars to jump start conversation and generate revenue.

Talk about a fruitful investment. Mason Arnold relishes the attention he and his com-pany garner around Austin for driving a vehicle with a big banana on the roof. In turning people's heads, he has turned a company car into a rolling conversation starter, brand fortifier and revenue generator.

"It's the best marketing thing we've ever done,"

Arnold says of the vehicle, one of three fruit-topped Toyota Prius hybrid cars operated by his 8-year-old company, Greenling, an organic-food delivery service.
