70’ Duster 340 4 speed value

But not everyone that springs to buy a REAL 70 340 Duster is worried about every minut detail of correctness, you left off did it still have 1970 air on tires?
Original correct cars are loved by those that have studied every detail as they came from factory. I total agree all you mention has a lot to do with value, but not everyone is so concerned.
Anything paid over the price of scrap is salesmanship!!
