HORRIBLE!!! SCAMMERS! DO NOT SPEND A DIME AT ANY MARK MITSUBISHI !My three year old car that I bought from Mark Mitsubishi , yes I admit didn't change oils regularly , they stated I screwed up the whole mechanic of my car giving me non stop negative diagnosis !!! Telling me, they don't want to fix my car nothing they can do telling me I need to but a new car or pay them $7000 for repairs !!! Threw a fit at dealership and left ! I ended up going to Sun devil auto on bell and tatum, they told me the service department were full of crap all I needed to do was change the oil and filter! My car was back to running perfect ! The bill was $45! Had no problem since!
