We have two 2006 Toyota Corollas- one an CE and the other an LE that we bought brand new. They are both standards. My husband changes the oil/filter every 5-6k miles and checks and changes the air filter regularly and adds coolant as needed. The LE currently has 168k miles on it and the CE has almost 120k. Neither has had any issues at all with the exception of needing new bulbs for the headlights. He has also changed the brake pads on the LE even though they seemed to have quite a bit of wear left. Both are driven 70% highway/30% city. I would like to see them both get to the 250k mark if possible. Currently they are both running just fine and seem to have no issues, getting about 37-38 mpg. What maintenance would you suggest or what problems would you be on the lookout for? Honestly they have only seen a real mechanic when we had a recall and nothing was said about them needing work... but then again I did not ask either! Our closest Toyota dealer is a good 50 miles away and I don't know any local reputable mechanics... but will make the effort if it is warrented.
