This 1970 Dodge Charger R/T is a rare factory sunroof car, but there's a catch.

HEMI-equipped cars are probably the rarest and most desirable Mopars from the golden age of muscle cars. However, collectors are also looking for all sorts of options that were ordered in very limited numbers. The sunroof is one of them.

Sunroofs were added to the option list in 1969, but they weren't very popular at first. According to the Mopar Sunroof Registry, Chrysler installed fewer than 5,000 of them from 1969 to 1972. That's an average of fewer than 1,200 sunroofs per model year, spread across several Dodge, Plymouth, Chrysler, and Imperial nameplates.

More than a quarter of those were installed in Dodge Chargers. The same registry lists 1,256 of them. This 1970 Charger R/T is one of those cars, and it was produced in the lowest-production year for sunroofs. Specifically, there were 176 factory sunroof vehicles made, a figure that includes the base and 500 models, as well as one unit shipped to Canada. If we narrow it down to R/T versions, it’s one of only 112 built.

However, this Dodge Charger R/T had lost its original sunroof and was restored with a replacement unit. This isn't a major issue given the scarcity of these cars, but the replacement sunroof is not a period-correct Mopar part. According to the listing, the Charger was equipped with a glass sunroof from an unnamed Mercedes-Benz. There's no information on what modifications were required for the swap, but the listing states that the unit “works as intended.”

Otherwise, this Charger R/T is a finely restored example that appears authentic, save for the modified stance, disc brakes, and mismatched wheels. Other upgrades include a vintage A/C unit, a factory-style Bluetooth-capable stereo, and Edelbrock aluminum headers and intake manifold.

The Mopar has been restored to its original EK2 Go Mango color; the black vinyl top and Burnt Orange interior are also true to the original.

The 440 cubic inch (7.2 liter) RB V8 engine is not numerically matching, but is correct for the date. It is a four-cylinder version that was standard on the Charger at the time. It was factory-rated at 375 horsepower and 482 pound-feet (654 Nm) of torque. In this car, the big-block V8 is mated to a three-speed automatic transmission with a steering column shifter.

All in all, this Dodge Charger R/T is the kind of classic that Mopar enthusiasts will either love or hate. While its specs are decidedly rare, the car has plenty of upgrades that will shock even the most hardcore fans. On the other hand, it's a very lightly restored rig that will turn heads at classic car shows.

This Go Mango beauty is set to go up for auction at Mecum Dallas 2024 on September 7, and I'm very curious to see if it will break the $100,000 mark. Is this Charger worth six figures?
