I spotted Mirage first time on my visit to Karachi and it was awesome. Now I just learn about the price and it's amazing. I was thinking it would be over 1.5 Million. The reason we see lesser Mirage and more Swift & Vitz is RE SAALE VEALEU 
Otherwise you can see very good car reviews in different car magazines, online auto blogs and forums.
We owned a Vitz 1.0 and the best fuel economy was 18.5 kmpl while going to Taxila. 22.5 kmpl is excellent, even Vitz d.4d (diesel) doesn't cross 22 kmpl.
I really appreciate your decision to stand against RESALE and getting a REAL car for pleasure ride.
Drive safe, God bless you!
(Another plus of this car is, it's less likely to be stolen
)
