You still see the occasional 1981-84 "810 Maxima" on the street these days, sporting the confusing "Datsun by Nissan" badging of the era, but I'm talking about the 1977-80 810s here.
I haven't seen an 810, in or out of the junkyard, for at least a decade.
Anyway, wagons like this have managed to achieve a modicum of cool, if only for the same nostalgia-laced reasons that Freakies cereal now seems cool.
I'd like an 810 wagon, sure, but what I really want is an 810 coupe. It's a homely, odd-looking machine, with approximately 0.04% of the build quality of the Nissans that came a decade later, and its 120-horsepower 2.4-liter six didn't get its 2,800 pounds moving very quickly... but it's a weird Japanese sporty car that nobody bought, and I'd be proud to drive one. I wouldn't even wear a paper bag over my head while doing so.
By the time Nissan was building these things, the US-market Z car had the L28 engine and the 810 got the smaller L24 out of the earlier 240Z.
It would be fun to drop the 180-horse L28ET out of a Late Malaise 280ZX Turbo into an 810 hardtop coupe. Someday...
