2001 and 2002 models are excellent in terms of everything, good car might range from 6 - 7 lakh and if you add a little you can buy japanse car, which will offer exccellent milleage, comfort features without any problem...
bhai 2001 2002 model known as exis is the best city ever.
rock solid suspension. road grip makes you feel sticking to the road even at high speed. hyper valve gives hard time to any 1.3 car. shape is fantastic and come with all the powered things usually one wants like ps pw powered mirrors. ac is fantastic too.
con : bad mileage.
a good car is karachi will cost you 625k around.
