Park Min Young was one of the stars who were invited in the launching of Hyundai Veloster PUV in 2011. To spice-up the event, a "Veloster Relay Mission" was organized where different stars were asked to lead one of the teams to complete a particular mission. Minyoung was selected to lead the Sunflower (yellow) team. Their task was to paint graffiti on a yellow Veloster car.
Here are some photos from the event.
