Believe it or not, that was my car from 1986-1989, and again in 2005. I was under the impression it had been seriously rear-ended in 2009 (according to http://clunkbucket.com/return-of-bluebird), though maybe the damage was just superficial?
The back story (stop here if this is boring or too far off topic):
I purchased it in 1986 from the original owner, a now-retired teacher known as "Mr. K", who taught at Pioneer Elementary School in Sacramento, CA. It had around 70,000 miles at the time; I sold it in 1989 with something like 105,000). I drove it for three years, replacing the head gasket, clutch, radiator, rebuilt the transmission... you name it, it seemed to go wrong, but I always got it running again. I got to know the parts department at Turner Nissan VERY well. I eventually sold it to Earl Thomas, an attorney in Carmichael who collected (more accurately, hoarded) Datsuns. It wound up on a property he owned in Rio Linda and was eventually moved to the back yard of someone in Carmichael who helped Earl keep his "fleet" running. That person was forced by the county (I believe) to remove the cars from his back yard and advertised them on Craigslist in 2004 or 2005. I contacted him and yup, there was my car, with multiple broken windows, flat tires and water pooled in the floors. Thankfully it hadn't rusted (a miracle!) and the engine still turned by hand. It had maybe 4,000 more miles on it than when I sold it. It still had the Honda Accord seats and Kraco stereo I installed in the mid-1980's, along with the "93 Rock" bumper sticker on the dash covering where the vinyl had cracked. A ton of my original paperwork was still in the glove box, too!
I put on new (and too cheap) tires, a new battery, and got it running - if barely. Then sadly I had to sell it and my other Datsuns (at the time I had a really nice 1966 PL411 (currently named Daisy and living in Modesto), a 1970 1600 Roadster, and a 1971 1600 pickup). I haven't owned a Datsun since that time, but occasionally search for them just for the fun of it.
Here are a few of the Datsuns I've owned:
