Dustin Mellows was a delivery truck for Trophy Sparkplugs in the 1950s. This mild mannered van had a monthly route that took him through Radiator Springs. On one of his regular stops, Dustin had a near head on collision with one of the locals. Their almost fatal meeting turned into a collision of fate. The couple fell in love and moved to a nearby suburb of Couperville, where they are now enjoying their relaxing retirement together."
Dustin was seen leaving town in Sally's flashback.
