I have owned my Mazda 3 2.3 Automatic since 2006 at 14,000 miles. It actually has a rebuilt title so it was cheap. I now have 162,000 miles on it!!! original engine, transmission, ETC. Only have done regular maintenance mostly myself. changed oil to synthetic
when purchased, change every 5,000 miles. Still running like a Champ! I will drive this car until the wheels literally fall off!!
This is also the base model, roll down windows, no cruise control, manual seats ETC, may have something to do with not having any electrical issues at all.
