The Plymouth Road Runner is a major car in The Fast and the Furious Series.
The Fast and the Furious: Tokyo Drift
The Plymouth Road Runner first appears in The Fast and the Furious: Tokyo Drift, driven by Dominic, saying "I won it from my friend Han a few years ago", when talking to Sean Boswell. This car featured a grey paint job and had black wheels.
Fast & Furious
Another 1970 Road Runner appears briefly as a protagonist car in Fast & Furious (2009), driven by Letty Ortiz. On this occasion the car was destroyed, being flipped over multiple times and then it was set alight by Fenix Calderon, telling Dom "the last time I saw it, it was burning".
The car in Tokyo Drift is not the same as the one in Fast & Furious, since Letty's Road Runner is destroyed, which happens prior to the events of Tokyo Drift.
Fast & Furious 6
The car is seen again, as the flashback to how Letty died is completed. The car is shown being flipped over and Letty subsequently crawling out of the car. Fenix then shoots the car's fuel tank, causing it to ignite and the car to explode. At this point, the car is confirmed to be destroyed.
