1970 Duster 340-4spd
The car is extremely clean, but for the money being asked, 1968 - 1971 340 factory cars are completely restored, every nut and bolt level of detail, to an original presentation. So for this car, it should present exactly like a brand new 1970 340 Duster, right off the showroom floor, UNLESS you find a buyer who completely falls in love with all the changes you made, and MUST have your car.
The highest bid cars are the factory original - rare examples.
As an example, at Chryslers @ Carlisle in July, there were several 1968 - 70 340 Darts, Duster and Demons that presented as factory originals, matching numbers drivetrain, all ownership history of the cars fully documented, and nicely restored. Asking prices were in the $15 - 18K range and even those cars DID NOT sell.
With all the labor of luv and $$$ placed in this car, it might be best to keep it.
