I am given to understand that prices of cars in karachi are generally much lower as compared to prices of cars in the upper Punjab region.
I suppose that 17 inch alloy rims do add to the value of the car but they mess up the suspension of the car, and we all are very much aware of the road conditions in Pakistan. The 14 inch rim with a 70 aspect ratio tyre not only provides a smooth drive but also increases the life of the suspension as compared to the 17 inch rim with low aspect ratio.
My car is without the CNG Kit.
The offer for sale still stands at 790,000/- with a very slight margin of negotiation of say maybe 5-10K max
