Carl Sagan passed away in 1996, but the impact he left behind in the fields of astronomy and cosmology was nothing short of an extinction level event. He is probably best known in the public sphere for his work on the 80s TV series Cosmos: A Personal Voyage -- but folks close to him remember an inquisitive guy who cruised around Cornell driving a Signal Orange 914 and chatting into a dictaphone.
The current seller picked up this 914 in Ithaca, NY back in 2002, had some rust repaired and (for unknown reasons) decided to have the entire thing painted black. Due to what can only be presumed is inadequate prep, the black paint is now flaking off like the bark of a eucalyptus tree, revealing the original paint. Regardless, the seller claims this is the original PHOBOS and therefore has quite the provenance amongst astronomy/astrophysics/aircooled fusion nerds. Whoever gets this car next will probably want to restore it to its original glory...but it is going to cost a pretty penny.
