Okay, lets do it your way (I am not sure WHO ELSE in this world does it like this):
Assuming there are different types of drivers in Pakistan, and also taking in account the general awareness about driving habits and all the stuff:
5 Honda city drivers:
1-Me (I love the car <3 because in my style, it delivers more than 18KPL all the time)
2-You (Seriously doubt the car, doubt the people like me who claim anything above 15KPL for the vehicle, several are here on this very thread. Don't believe anyone because you're damn sure that if this was true, hybrid cars wouldn't be in mass production)
3- Baba Fareed (Typical aged driver, drives normally, picks n drops kids of a sahab jee in lahore, doesn't know a lot about the car, gets it tuned from thallay wala mechanics, and gets done whatever he finds useful because the sahab seldom gives a damn about the car, car delivers 13 KPL)
4- Ustaad Shabeer ( Typical professional driver, CNGed car, knows that honda sucks big time, TWO DEE is the way to go. CNG is banned nowadays so car is delivering no more than 7-8KPL )
5- Khan Bahadur (another one like ustaad shabeer, but all he does is drive a taxi honda city and knows one thing ONLY: time par pohanchna hai; 10 KPL mileage)
So here we go, the average fuel consumption:
18+15+13+8+10=64 and divided by 5= 12.8KPL
WAY TO GO! HONDA CITY SUCKS BIG TIME! PEOPLE LIE! YOU WIN! CLAP CLAP CLAP!!
THE END?
