Only twelve people ever ordered a 1970 Dodge Challenger R/T with a 426 Hemi and a convertible top — and just five came with a manual transmission, like this Plum Crazy Purple example from the Brothers Collection. The factory fender tag tells the whole story, down to the exact rear gear ratio and interior trim code. See how V8TV verifies a claim this rare, one code at a time.

Only ten 1966 Plymouth Belvedere II convertibles left the factory with a 426 Hemi, six of those with automatics, and just one in the color code 661 Metallic Mauve — the car in this episode, restored with its original numbers-matching driveline intact. Commenters can’t agree if the color is mauve or purple, but they agree on one thing: this Hemi was built to be feared, not casually enjoyed. What actually makes a car the rarest piece in a collection already built around rare Mopars?

This 1968 Plymouth GTX convertible is one of 24 built, not 34, despite what the video’s own description claims elsewhere — and Mopar fans in the comments caught the contradiction. Under the hood, a 426 Hemi rated at 425 horsepower but built for NASCAR carries torque near 500 lb-ft, backed by a rear end reinforced specifically to survive it. One commenter even corrects the entire GTX-versus-Road-Runner origin story. So which details actually hold up?
