> Current or past generation cars are comparatively "open" with lots of repair and maintenance options, which gives owners the benefit of choice and competition. Not necessarily. For example BMW and Mercedes will design their vehicles to make them difficult to work on, and often when a specific part breaks you need a proprietary piece from the OEM. Idk if companies like Ford and Toyota use the same tactics.
