When I was the age you are now I owned a factory condition metalic gold with the tan vynl roof 1969 Roadrunner with a 440 inteceptor motor.
The exact colors and everything just like thier 1969 commercial here.
Bought it and put the 440 in it even though it still had the 383 Magnum emblem louvers in the hood.
It was the car that the roadrunner door checks the coyote with.
And it's horn actually sounded like the cartoon roadrunner and I had it down "Meep,Meep" on the button.
