Most famous for Ralph Nader's campaign against it, the Corvair exemplified the forward-thinking American auto industry in the 60's: rear-mounted aluminum air-cooled flat 6, unibody structure, doors and front & rear windows are stressed members, among the first turbocharged American cars. While the developments were great, the Corvair wasn't without problems. Mounting bad press and safety concerns pushed GM to shutter the line in 1969 after 9 years of production.
Along with the CJ Jeeps, the Toyota FJ40 is one of the templates against which all off-road vehicles are measured. Yes, that's a lofty statement, but its undeniable. Toyota hit the nail on the head with nearly all the FJ models (current mall-buggy 'FJ' Cruiser blatantly excluded). They have nearly indefinite service lives, are engineered to be repaired in the field with whatever is on hand, and are about as basic a vehicle as one can find.
