Fleet advertising offers the lowest cost per thousand (CPM) of any mass advertising mediums, based on research conducted by Outdoor Advertising Association of America and Fleet Advertising Media Group. Advertising expenses are typically calculated in cost per thousand or CPM, as in how much it costs to reach 1,000 people.
Consider the cost to advertise on a billboard. You must have the graphics printed and rent the space (anywhere from $1,200-$30,000 per month in Colorado). With vehicle graphics, your billboard is mobile, costs much less and you don't have to rent the space. You can use the money you'd spend to rent billboard space toward your car lease or loan. Even with a full wrap on a vehicle, you can pay off a new car in a pretty reasonable amount of time vs. tossing money at a billboard.
