My Mirage impresses year after year.
I have been driving my Mirage over 6 and a half years, and even now, I can't believe how good my car is on gas. 45 MPGs all the time. Winter less but still good.
I filled up today for the first time in literally two weeks. That means I got over 550 km's with my last tank, adding my commute and weekly grocery runs.
That means I am spending about $12.25 a week on gas right now. Insurance and car payments not included (and upkeep/maintenance costs, and I dote on my Mirage).
