Bro, go to New MA Jinnah road for a price check. What they quote, add 40k to determine fair market value. My near family member has bought a 2008 RXI,petrol, Shell company used car in silver color. The car is just 72k driven and the price is too low. Since you have an lxi, and newer model, i believe it will fetch somewhere between 6-625 in karachi.
