There is an end to everything. For Plymouth, it had taken a great deal of money and effort to get Richard Petty back in its brand for the 1970 Grand National season, to the extent that the company actually met the increased homologation standards required by NASCAR to build an aerodynamically styled vehicle. Creating 1,920 street versions of the Superbird was the result, and a number of them remained in dealership stocks far after the model year concluded. Nonetheless, the savviest franchises recognized exactly how special these cars were, and a handful were deliberately tucked away for posterity. In fact, the unrestored car shown here is thought to have been the final-ever Superbird sold as a ‘new car,’ as it was titled for the first time ever in 1985. Originally delivered to Brown Motor Sales in Grafton, West Virginia, this vehicle was built with a U-code 440 Super Commando engine. Between 1970 and 1985, Brown Motor Sales was renamed George Motor Sales, Inc., and after it changed hands, it was featured in the June 1989 issue of “Muscle Car Review” magazine. The driveline consists of the matching-numbers 440 4-barrel engine and A36 Performance Axle Package, which features the A727 TorqueFlite, 3.55:1 Sure Grip differential, power front disc brakes, and Hemi-type cooling and suspension parts. Inside, the car features duo-tone vinyl covers on the fold-forward bench seats, Solid State AM radio, and 150 MPH speedometer. Now showing a believed-correct 14,350 actual miles, the provenance on this original-finish Alpine White car is impeccable. In addition to remaining in the original dealer’s possession until 1985, the car is accompanied with copious documentation including the original broadcast sheet, window sticker, invoice, bill of sale and the copy of stock car eligibility certificate. From the black vinyl top to the hood pins, Rallye wheels and Goodyear Polyglas GT tires, presented here is an unmatched opportunity to own an original and fully documented Mopar rarity from the aero-war era.
