You have to remember it is a 1973. No mater how rare it is still a 73. 72 and down cars will always be worth more. 73 and up just are not as popular. You must remember it is not a Hemi car, and the economy is crap. The value of all cars is way down!
I do not know were you are getting your numbers, but to say there are only 12 left is just nuts. I am sure they made more than 40 of them.Just do a search on line. They are all over. If you never got an answer how do you know how many were made? I would like to know to. I think it is an interesting car.
WOW! You guy's are hard! Production was only 40. Of those 40, 12 are left! This is one of 6 automatics. Of those 6 how many are 340's. I mean 40 that's less than one per state. Never got an answer, as to how many 340 spacedusters were built!!!!!
