Wow! Just read all 20 pages of this thread, very interesting discussion of this topic. My tastes for these supercars fall on the side of all original in condition for ownership/collectibility.
I believe the value associated with these rare musclecars should certainly be relevant to the condition of the vehicle. An unmolested, orginal in factory condition as built should be worth the absolute most. There can be nothing like it to compare with. I think the word original is very much overused, and is not proper to describe any part of a car that has been refurbished, restored, rebuilt, repaired, etc. My opinion is that a car that has been tampered with in any way, no longer is the same car that was factory built. Replacing most of the sheetmetal or rebodying a vehicle has the same end result, it is no longer the car it started life as, period.
Probably, none of us (or very few) have a vehicle that can be considered original.
