You know the old saying " everything keeps falling off, Toyota", is true, the body rots away, the doors stop locking, the windows fall out, but the engine and drivetrain just keep on going, and eventually the oil leaks keep the rust at bay as well.
I learnt a lot about auto body repair owning a Toyota, replacing panels, doing rust holes and how to use "pre loved" parts from the mangled heaps at the local scrapyards. Even did the engine as well, but never had to do anything to the manual gearbox aside from seals and checking the oil level.
