Japanese cars have never deserved the reputation they have now. My neighbor bought a new 68 Toyota Corona(Camry, today), in 2 years it rusted so bad it buckled in the middle and the doors wouldn't shut. We sold Couriers(unfortunately) to people who traded in Toyota's and Datsun's with rust holes in the floors at 2 years old and shift levers pulling out of the floor. I said 'unfortunately" because rust would bleed out of the body seams wile under 12/12 warranty. We took in a 2-3 year old Honda Accord with gaping rust holes in both fenders and the rear quarters that would fog the driveway with oil smoke when it was idling. We sold our first Escort wagon in the fall of 80 and took in a 78 Subaru in trade. Subaru luckily used to mount the spare tire above the engine, the front suspension had rusted so bad the shock towers collapsed against the tire. Magazines like Consumer Reports created the Japanese mystique, when the Mazda Navajo was introduced, CR said it felt "tight and Japanese". The first few years came with double sided Ford keys. A few years ago CR announced that they would no longer give Toyota's positive reviews WITHOUT DRIVING THEM- for years they just rubber stamped Toyota's as good vehicles. Just ignore the pile of rusted frames behind our local Yota dealer and the occasional unintended wide open throttle without stepping on the gas. This post is too long already so I'm not going to get into Takata air bags.
I havent owned a japanese vehicle in a very long time (last one was a civic believe it or not i got in a trade deal i had for some other shit)
But since i dont much care about their cars ill talk about their trucks....
Fair warning like most of my outlooks its prolly outdated but here we go...
Every japanese truck ive been around (as in, knowing who owns it) has been weak. Weak in the sense that compared to the american counterpart, it had less power, less durabilty, and would not take abuse as well as something american.
When i first bought rusty #1 a buddy of mine had a (at the time) couple year old Nissan/Datsun truck. Compared to the ranger it was flimsy, underpowered, and wouldnt do half the stuff my ranger did.
Japanese trucks are fine and reliable for the guy who does nothing but haul a few 2x4s home from lowes, but when you really start to use them they fall apart like tissue paper.
