I read a few years ago that American cars have less mechanical problems as the Americans spend the majority of the development money on the engine/drivetrain mechanicals making them more robust and less on the interior which is why the interiors look cheaper than European cars. In the same article it said European manufacturers spend more on better interiors and have less money to spend on engines/drivetrains, hence the amount of faults on them. From your experience, are American cars more robust and reliable mechanical wise?
