I prefer the earlier C3s, but this one is among the most desirable '74s with the BB/4-speed combo. Seems a little rough around the edges for the $19k asking price, but I'm not well versed on this market by any means.
The LH fender to door gap looks odd in pics - probably worth checking out in person before taking the next step.
