The Dodge Challenger’s enduring appeal stems not only from its handsome styling, but also its ability to accommodate the entire Chrysler engine range by virtue of the front sub-frame, which was borrowed from the B-bodied Charger/Coronet. In addition, the use of the Charger/Coronet rear suspension layout provided a wide rear track that could house larger wheels and tires. The result was the so-called E-body, which would underpin both the Dodge Challenger and Plymouth Barracuda. Launched for the 1970 model year in coupe and convertible variants, the Challenger was a late arrival to the muscle-car scene. Despite being tardy, it did gain popularity with wild colors, vast options, and an impressive roster of powertrain combinations.

One of the more appealing trim levels was the high-performance R/T or “Road and Track” option package. It included all the standard Challenger features and added an electric clock, Rallye gauge cluster, Rallye suspension with front and rear sway bars, heavy-duty front disc and rear drum brakes, fiberglass belted tires with raised white letters, and special striping.

This example is believed to be just one of 1,070 R/T convertibles produced for the 1970 model year. It left the factory finished in Plum Crazy Metallic over a black vinyl interior with a black soft-top and was equipped with the optional 440 cu.-in. “Six-Pack” V-8 engine. Breathing through no less than three Holley two-barrel carburetors, this desirable, high-output engine was rated to produce an impressive 390 horsepower. In this example, it is paired with a three-speed Torqueflite automatic transmission.

Code stampings on the fender tag indicate that this Challenger R/T was further equipped from the factory with power steering, power brakes, power convertible top, dual exhaust system with bright tips, hood tie-down pins, longitudinal sport stripes, power windows, bucket seats, center console with woodgrain trim, painted racing mirrors with driver’s side power adjustment, tachometer, Rallye gauge cluster, and 10-watt AM/FM stereo.

The car rides on Goodyear Polyglas GT tires with raised white lettering mounted to Rallye wheels featuring polished trim rings. Presented with a remarkably clean undercarriage, this highly optioned Challenger R/T convertible is said to benefit from 15 years of single ownership and is accompanied by a black vinyl tonneau cover and a space-saver spare.
