if you want fuel economy, buy vehicle with CVT transmission (PRNDSB). Also make sure its 2WD (L275S) will be chassis code. Make sure the car is a minimum of 4 grade...
For market value, someone in Karachi can guide you better.. roughly somewhere around 8 for a clean car.
I have 2012 CVT and the fuel economy is amazing. Plus, its not as small on the inside as one might think. Its so good that it has become my daily driver
