My sincere suggestion: Avoid going for FAW V2.
Drive wise, FAW V2 is excellent. Fuel efficiency depends on your driving styel, road conditions, persons in car, luggage, etc. With light foot, on highway travelling, 02 persons on-board, it used to give me somewhere around 12~13 kmpl within city (if I can recall correctly), but some owners were not able to get more than 7~8 kmpl.
If fuel consumption does not bother you, then Swift all the way, despite the fact that it is not value to money.
