$3k is unusual for a Mirage (unless it's damaged). I've seen
a couple of undamaged ones between $4-5k recently, but even those are outliers with higher than average km.
(NOTE WORTH REPEATING: despite the ratings, the 5MT gets better fuel economy than the higher-rated CVT in the real world in the hands of an attentive driver. No "extreme" techniques required. But add in the techniques and silly numbers are possible.)
