660cc ki average 20km hy.
Logon ki 2006 wali Altis auto bhi within city 11-12km krti hy.
The same cars, when come to us average a lot low than what is quoted by the previous owners.
I will again politely disagree with the mileage. It is only possible when you play with the diesel pump and control it from there.
As far as your own jeep is concerned, it is a manual and most Importantly, it is yours. Exceptions are always there.
