Can I make money advertising on my car, or is it a scam?

Car owners can make extra money advertising companies on their cars, known as “wrapping,” but some solicitations to join such advertising companies are scams. Legitimate advertising companies pay sums that amount to a little extra income per month to drivers to wrap their cars with ads. Scams advertisers may send solicitations to car owners offering lots of money upfront, but people who respond to such solicitations usually never hear from the scammers again.
