The Datsun 810 became the Maxima for the 1982 model year, but the Datsun-to-Nissan changeover hadn't taken effect yet. That means you're looking at a very rare Datsun Maxima wagon… and it's doomed.
It's in very nice condition, too, but apparently that wasn't enough to induce anyone to pay $200 for it at the pre-junkyard auction.
Of course, you all know why I was poking around in an old Maxima. That's right, I had to take the voice warning system box, which uses a 3" phonograph record for a "brain." Now that I've got two of them, I can set up my Datsun Warning DJ Console and start scratching!
