Turns out mine's pretty old as far as North American Mirages go.
August 2013 - production date (on the Mitsubishi Motors placard on the driver's door jamb).
It could very well have been on the first shipment to Canada. The first Mirage shipment set sail for the U.S. west coast in late August, 2013.
The first shipment of Canadian Mirages arrived on September 10, 2013:
(I believe that's the Fancy Metro in the back row, 2nd from right. )
Arrived at the dealership October, 2013.
That kind of provenance means it's worth more money, right? Mirage collectors, submit your bids now!
It had a somewhat unusual life before its first owner too. Looks like it sat around unsold for a long time: until March, 2015.
