Conclusion
The purpose of the build was to create a one off unique street/strip vehicle. No other Plymouth
Duster or its sister Dodge Demon looks or acts like it. The car throws you into the seat off the
line, pulling like a freight train through the all gears. Yet, still manageable around town to cruise
and enjoy the scenery. The car was designed to be driven and enjoyed partly because it started
life off as a slant 6, automatic, bench seat base vehicle. Today, the vehicle is a good
representation of a Mopar Classic combining the best of modern technology and classic styling.
Why am I selling this car?
I have many memories with this vehicle and have enjoyed a decade of smiles, laughs, and
burning rubber. But I am looking for more excitement, particularly from road circuit courses. I
am in search of an Italian vehicle to road race and complete my Italian bike collection. The
history of my youth working with Ferraris has led me to pursue one.
Pricing
It is hard to price a vehicle modified in a way to enhance the performance and reliability yet
compete with a fully restored 1971 Plymouth Duster 340. On the other hand, it is one of the
most desirable years for Mopar with the sharktooth grill, curious yellow paint only offered in
1971, and favorable performance parts.
I would categorize this car as a quality driver that can still be shown at car shows.
I have priced this car at $25,000 – which all things considered should be in a sweet spot for
buyers based on what has been done and is included.
