Dear Prices mostly depends on condition of the car and it has nothing to do " mostly " not always with models of the car, if an old model car is in genuine condition then it can sell at a higher price than its current market prices but for your information:
Approx. Prices of normal conditions of vehicles you mentioned will be:
Suzuki FX 1985 w CNG ( Rs. 85000 to 90000)
Suzuki Mehran 1995 w CNG ( Rs. 180,000 to 200,000)
Suzuki Khyber 1995 w CNG (Rs. 250,000 to 280,000)
Hope i have quoted here the most feasible prices as far my experience is concern if wrong experts can comment.
