Just make your own decision, if u think u can get something bettyer in your budget, go for it.
Based on my usage of this car for last two years:
It gives 9-10 Km/Liter in city
11-14 Kms/Liter on Highway (depending on Speed)
On CNG, performance is average
2+ Rs./Km in the city
1.75 Rs./Km on Motorway
less then 1.5 Rs./Km is possible on continuous speeds of 80-100 Km/h
The car is heavier then any other car around which makes it less economal.
Drive feel, features, suspension, reliability is very good.
DOHC, 16 valve engine has good life, no major problems reported with Dewan regarding durability and engine life.
Pick, performance, speed is average, nothing sporty
Its a liftback sedan with lots of space, even with CNG.
In ISlamabad and LAhore second hand parts are available with some kabariyas.
Routine maintenance costs less then a Toyota Corolla or HOnda.
I have given u facts based on my own expereince. I personaly have no problem with the car, sonsidering what i paid.
