Most of them are ragged on like crazy and not maintained well. The only way to ensure it's taken care of is to get one new. Also, as far as major recals, some models before 05 needed to have their engine's "tested". If it failed, they needed a whole new engine. Problem is, Mazda won't say what they test for aor what's wrong which is really scary as to what is wrong with those engines, and what is preventing it from happening again.
