Researching the plate number, it looks like this car was on the road at least as late as 2013 when someone made an abandoned vehicle complaint about it. It looks as if it was registered to someone named Terry Lee. Unfortunately the only photos I have left are black and white, but according to the S.F. Parking & Traffic documents, it was blue.
Renewal fees show some info. It looks like someone had its registration paid till June 2017. It's a 74 which is most likely the only reason it's been kept.
