Methods and devices for dispersing scent around the exterior of a vehicle. A scent-dispersing device is attached to the exterior of a vehicle. The device is configured so that the airflow through or around the device causes scent to be dispersed around the vehicle. In one embodiment, the device is installable in the tailpipe of a motorized vehicle so that the exhaust passes through or around the device and thereby disperses scent into the area around the vehicle and into the surrounding environment.
