Just to remind y'all: YES, they used a '74 Roadrunner which appeared in 5 of the first 9 episodes, then beginning with episode 11 they switched to a '71 Satellite Sebring in a Roadrunner paint scheme, hoping nobody would notice (we did). Some prefer the '74; personally I prefer the '71, finding it much sleeker and meaner looking with the wraparound bumper/grill assembly.
Base kit is the Revell/Monogram '71 Plymouth GTX. Modifications include:
-Replacement hood
-Smaller-block engine (from 71 Duster)
-Completely rebuilt & boosted rear suspension
-Replacement tires
-Wheel hubs from '77 Ford van
Additionally, all GTX logos were removed (not easy on the grill); headlights made from sanded/polished acrylic gemstones; engine bay heavily wired and detailed; scratchbuilt steering wheel, CB radio and antenna; paint is Plymouth Yellow Blaze.
