“The Plymouth Duster is Mopar's underappreciated mini muscle car” -Hagerty Media, October 2020

Hagerty went on to explain their view: “Mopar built some of the loudest, gaudiest, most cartoonish muscle cars of the '60s and '70s. They were perfect. You couldn't ask more from a muscle car. Consequently, muscle car fans have driven the prices for the hottest Mopars into the stratosphere. Plymouth 'Cudas and Road Runner can demand six figures when equipped with the right powertrain and color options. Plymouth Dusters, on the other hand, are still attainable, even when equipped with desirable powertrains. Sure, they didn't pack 440 or 426 power, but they also weighed less than the B-body Road Runner and Satellite and make an excellent platform for a street or strip car.” As to the Duster 340, they added: “From 1970–73, the Duster 340 offered up a potent small-block package with the same high-revving power as the 'Cuda.”

Offered here is a beautifully restored and respectfully upgraded 1971 Plymouth Duster 340 in medium blue metallic-over-two-tone-blue vinyl. Showing 62,000 miles (roughly 1,250 miles per year on average) on its odometer, the car retains its original appearance, much of its factory-installed equipment, and most original parts (including the steel factory wheels) that were removed are included in the sale.

The car's exterior medium blue metallic paint is in exceptional condition, professionally applied and uniformly glossy across the entire car. A full “Duster 340” graphics and striping package—including a large “340 Wedge” hood decal and the cartoon “Duster guy” rear-deck graphic--are perfectly applied. There is no mistaking this Duster for anything but the street-performance muscle car it is. The chrome trim, bumpers, and badging on the car are original and in excellent condition; in the same way, cabin glass and lighting lenses are clear and undamaged. Exterior racing-style mirrors with black finish are mounted, as are aftermarket 17-inch chrome wheels (with Cooper Zeon RS3-H high-performance tires), and chrome dual-exhaust tips.

Inside, the car's original interior is in place. High-back front bucket seats and the rear bench seat are upholstered in square-pattern two-tone blue vinyl and exhibit near-perfect condition; there are no rips or tears. The complementary shades of blue are particularly attractive. The factory dashboard with woodgrain trim remains in place with added instrumentation in the form of a steering-column-mounted Auto Meter tachometer (with shift light) and a trio of auxiliary gauges added below the dash, a look perfectly in keeping with modifications many original owners would've made to their Duster back in the day. Also added is a Panasonic audio head unit mounted in the factory radio location. Medium-blue factory carpeting covers the cabin floors, and the 4-speed manual transmission shifter is mounted on the center-tunnel hump.

Under the hood, the perfectly clean and orderly engine bay is a Mopar fan's visual delight. The air cleaner cover sports “340 Four Barrel” identification and valve covers are “Mopar Performance” branded. Auxiliary components are properly located; hoses and red distributor wiring are neatly routed. The car's original build tag remains in place. (A variety of the removed engine parts can be seen in the photo gallery.) Viewed from below, the car's chassis is exceptionally clean. Massive performance headers, the full-length dual exhaust, suspension components, and the four-wheel disc brakes compete for attention here.

This extremely well executed, performance-upgraded 1970 Plymouth Duster 340 is faithfully presented from every angle (including from below) in the more than 170 high-definition photographs and the short walk-around-and-startup video available at the GarageKeptMotors site. That said, we always encourage in-person, up-close inspections by interested parties—or their representatives—at our Grand Rapids, Michigan showroom. We ask only that advance appointments be made by phone or email so that we can devote our full attention to our visitors and this very special automobile. In the same way,feel free to send questions our way via phone or email. Our showroom is not open to the public.

The Mopar fan who acquires this exceptional '71 Duster 340 is certain to spend almost as much time enjoying the street-performance aspects of the car as he or she does showing off the many details of the car to fellow Duster fans. Saturday-morning cars-and-coffee gatherings ought to be a blast.
