Thats a really good WARRATY. better than ours which is 18 months free parts warrantied replacement and 50% off labor for replacement for the duration of the manufacture stated warranty for the parts. There is a couple of additions and exception depending on some parts like some brake parts , batteries, rebuilt parts etc. but no need to mention the details or all of them.

I think you will do well and have a good reliable Mazda for the duration of your ownership. Just keep up on the regular services and if you get the check engine light at least have the ECU scanned and see what up.
