I just did a quick search on Craigslist for SF and Bay Area and surrounding cities. It showed 139 986 for sale at this time. There are duplicates but even if you cut the results in half you still have around 70 986's for sale just in the Bay Area alone. Definitely not a rare breed at least for California. Maybe in 20 years when most of the 986 have been recycled where the values go up and it will be considered rare.
