This car was listed once before, and "only" got up to $7,600 (which I feel is about what it's worth).....reserve not met! So he relisted it, and this time he got what he wanted....

Too much IMO despite the condition, but MAN is that one of the cleanest ones I've seen in a long time, if not ever. I've seen several really nice/low mileage ones go for well above what your typical car of that era in similar condition sells for, though this is the nuttiest price yet. Perhaps there's still a possibility of these becoming collector cars in the future.
