I purchased my 2015 Mirage new in 2016 for $10,200 which included tax, tags, and title and it now has 82k miles. I've averaged over 40mpgs without even trying. My only issues have been a bad heater core (which a fellow forum member replaced for me) and a bad driver side window regulator. Other than that it has run like a Singer sewing machine! I put after market rims on it which gives it a nice profile. Beyond that it's occasional oil changes and basic maintenance.
When I purchased it in 2016, I wasn't in the market for a new car, but the local dealership was offering $3500 off MSRP, making it a steal at $10,200 all in. As a Geo Metro guy I was looking to continue with 3-cylinder tradition, and the Mirage fit the bill. I'll drive it until the wheels fall off!
