i think its worth around the high end coin mentioned here
and the main reason is not for what it is!!!!...

you can argue about its a less wanted 72,missing its orig motor or anything else
what you cannot dismiss or blow smoke over is

just look at the attention it attracts!

imo
that adds a extra intrinsic value
you cannot/will not get with most other cars....
and it out weighs the negatives by alot.

to put a number on that is hard and will depend
on how bad the next owner wants alot of attention..
