Today is my 1 year anniversary owning my '17 G4 SE. I have to say it has been a good year with no major issues and incredible fuel economy. I do not have a work commute so she only has 6959 miles as of her at her 1 year mark. 2100 of those have been round trips to my hometown to visit family. In fact I just completed a 750 mile (1207 KM) trip at 42MPG, cost me all of $28.00 for the trip. That was less than one fill up for my old Buick. The G4 is not bad on the highway, just a bit noisy but turn the stereo up and all is ok.
Only problem has been a fuel door that keeps breaking. Won't open from inside, I have to pry it open with my key or something similar. Been fixed twice and no one seems to know why it happens. Small potatoes.
Would I buy another? Sure would! Economical, comfy (I love my heated seats!) and dead reliable.
Love my Mirage!
