Dear Friend! If fuel efficiency and quality is your prime concern and you want to keep a car for at least 5 years w/o being worried about it's resale, I would suggest you to go for Mitsubishi mirage. I own both mirage and cultus and fuel consumption of both cars is almost the same. Cultus has the advantage of more resale and availability of local dealerships while Mirage is equipped with the following features which Cultus owners can only dream about;
Digital Climate Control
Idling stop/ECO idle function on signals etc
Traction Control
Automatic folding side mirrors on remote key
Auto Headlights
Push Start in G trims
Solid body comparable with Cultus
Rear Wipers, Wiper speed adjustment etc
CVT transmission which is better than normal Automatic
There are numerous other small functions
Plus you can get a clean less kms driven mirage within 1.4 Million PKR.
