This is a genuine, factory-produced RM21 Road Runner, finished in the highly desirable high-impact color of F6 Rallye Green with special blacked-out hood treatment and black vinyl top. The power is supplied from an upgraded Chrysler 426 HEMI dual- quad engine backed to a numbers matching 727 automatic transmission. The chrome and stainless pop when rolling on 15x7" chrome Magnum 500 wheels and correct Polyglas red line tires. The white and black interior is in excellent condition and compliments the green exterior well. The undercarriage is also in excellent condition; finished with a light undercoating and detailed to resemble the topside.
