Great question..... The research I have done suggests this is the last remaining example of the car. That doesn't mean it is worth anything, just that it is the only surviving one. However, if I were to buy it, I would bring it back to near new condition.....
I would stab at it like this:
Engine rebuild: $ 5000 (you know it is missing some parts)
Drivetrain surprises: $ 3000 (Custom something will be necessary here)
Interior / electrical: $ 5000 (I would think pretty easy stuff)
Bodywork / paint: $12000 (requires hand made trunk lid + surprises)
=============================
Total Invested: $24000
That would be with me doing all the grunt work like reinstalling the engine. Pulling all the parts off the car before heading to the body shop, installing interior panels, etc.
The guy is asking $20,000 for the car.....so is it worth $44,000? ?
