Such an easy question, without an easy answer. I've been trying to figure this out as well.
My car is in better then average condition but not outstanding. This isn't a time capsule. I enjoy my cars and do drive them. My car currently has 34,000 miles.
NADA says the value is between $27,000 and $36,500 without the Aerobody.

$10,000 more can easily be added for the Aerobody.
With only 500 of these cars ever made, they simply do not trade hands enough to get an accurate read on the value of this rare option.
That being said,
$32,000 in today's market or a very interesting trade and cash.
