There are good dealers too, mecca motors, danish motors they never disappoint you, i know there are lot more good dealers and if you find something wrong you can always complain.I will prefer to buy vehicle with maintenace history anyday may it be mehran or civic.
Just want to say that Remove Pak suzuki dealership from Pakistan and Wagon r will be 1 lac more cheaper from the day dealerships are gone, Price is dependent on many factor so as resale. And after sale service and parts availability is of key importance once vehicle is 5 years old.
