Your argument is not concrete. Not all jap makes are problematic. I've been driving 2003 Vios till now no major issue only seat belt rosak and gasket oil leak. My friend's relative had been driving an old Merc he said every month have to spend 4 figures to fix various problems.

About safety having more airbags doesn't mean it is safer. It is about your driving altitude. My house has a Kancil no airbag since 2002 till now only light bumper to bumper accident.
