I had some similar budget a year back , had 2 options in sight which were best.. A new swift or city.. 10.5 was my range and started searching a city on pakwheels, got hold of it with in 5 days . The car was 35000 driven January 2007 model , white color. The drive and the condition spoke for it self which confirmed the mileage was not altered. Only the front bumper was painted. The car asking price was 11.25. bargained a bit , raised my range to 11 and finally bought. Now the car is 49000 driven , still going perfect and simply loving it.
The car also had cng. I highly suggest you to look for a city , take out some time and find a good one. You will surely be satisfied with your purchase.
