Sorry for spamming but this is the last post (for now
) ... [edit] it got very long un-intentionally
My experience and findings :
I bought a 4 grade, 2012 , X trim , Silver color, 16.5K mileage. It reached lahore in around September end.
Fuel Economy:
21+ Km/L with full AC in-city (lahore) (in sept-oct)
23+ Km/L without AC in-city (lahore) (when weather got colder)
This calculation is with manual tank-full method. The digital meter shows almost same (22 and 24). From start I have been using HOBC mixed with regular with 40 : 60 ratio.
I drive with medium foot on main roads I easily go between 60-90 with rpms between 1800-2500 I only (eco).
I easily touched 110+ speed on ring road with 4 passengers on board.
when I received the car, I took it to a good oil station for getting new oil and filter etc. but the guy there checked it and showed me that all things , oil + filter + air filter and CVT transmission oil are all new and v good quality so no need to change and you can drive it for atleast 2-2.5k kms easily. Its almost 2.3k driven as of writing of this post. will be taking it for oil change soon.
My experience:
It has been totally awesome. Before it, I had Coure and driving it was like 'jabri mushaqqat' . I avoided driving it as much as possible, for home chores etc.
But this car!, its a absolute pleasure driving it, like literally!
Automatic CVT transmission its like driving a breeze.
The car speed-o-meter itself tells you how to drive most fuel efficiently.
Automatic Air conditioner , Power windows, power steering , power side mirrors , front and back defogger , back wiper , built in sound system with 2 front and 2 back door speakers (very good audio) , driver and passenger airbags and many more accidental security safety features in body.
Immobilizer , as of yet not broken/hacked security system, makes it one of the most secure car security system.
Lots of space .. easily accommodates 5 persons (medium build) + 1 child (front middle as the driver seat joins with passenger seat). The trunk also has a 'lot' or room.
A bit of back story, if you have waela time 
There were some doubts and concerns in mind by people's comments that buying a 660cc in the price in which you can buy either new pkdm wagonR 1000cc or some older vitz or honda City , and that it wont have resale , expensive maintenance , blah blah blah .
But after driving my uncle's Honda Fit and Vezel ... and also the fact the JDMs have lots and lots of feature which pkdm doesn't and also the fuel economy. I had decided in my budget and fuel economy requirements JDMS is the go.
I was initially looking for Mira E:S but then I read somewhere on this forum a comment by a veteran pakwheel-ian and importer of lots of JDM cars that WagonR has more functionalities like dual battery and dual folding seats front and back more space etc.
That triggered me and I did research and also went and looked and tried to JDM WagonRs in local market. Its totally personal taste but I liked the interior and overall look of wagonR more than Mira ES.
Spending a lot and lot of time on pakwheel forums I learned one thing , never buy a (so called) 'fresh import' JDM without verifiable acution sheet. Spent almost a month looking around JDMs locally I found out that almost of them first of all wont show you auction sheet, or the ones they show are not-verifiable . I also found out that most are R grade or accidental and are repaired locally such that almost noone can check and tell that its repaired and they show you false auction sheet that it 4 grade.
So at last I decided to import car myself through an importer where I can chose everything and also know that the car is not repaired .
After carefully bidding for 2-3 weeks, got a 'very' good condition 4-grade silver color with few very minor scratches .
