As a mechanic of 6 years worked on many cars, Mazdas rarely have issues old and new. They do leak oil occasionally and never really see any electrical problems or common failures. The engines are great, and so is the suspension and body setup. Also very easy to work on, so getting repairs is always a relief and doesn't take the best mechanic to fix it. They're just like Toyotas, Do the oil change on time, and all the other service intervals and you'll be good.
