Analog systems can be difficult to troubleshoot too, depending on the issue. I've spent some time scratching my head on some old turn signal systems on old motorcycles before, and their diagrams looked simple... at first. Digital electronics can be a pleasure to work with if you have the right tools, the right information, and the system wasn't designed poorly. The Suzuki and the Impreza aren't just more complicated for no reason -- they're also most sophisticated vehicles that do more things.
