From a former mechanic's perspective:

-Easy to work on although a bit cramped.
-Parts are always easy to find for most models


I don't recall them having any specific problems but, then again, I never really worked on all that many of them during my time as a mechanic. Mostly worked on Mitsubishis, American models, Toyotas, Hondas, and Nissans with a dash of German cars like VWs.
