Datsun B 210... forget the year.... early 80's iirc. Not a 'bad' car.. I did rat it out.. 5 spd... kept oil in it... it kept running.
Worst car might have been an 80's something Nissan Sentra wagon, but only because it threw a rod.
Right now I also have an '86 Truck (pathfinder, but not called a pathfinder) with 200k on it... I'd call it a good truck, even though it is the ugliest car i've ever owned... and I've done some body work to it to get rid of crunched fender and such.
