Well in a year had an experience to visit Samanabad & Defence used car markets beside jail road to buy n sell three cars.
my observation till todate is that all car dealers skin you to the maximum once you buy a used car & depress you to the optimum once you present even unregistered brand new vehicle , for their offer with margin of lacs.
Car dealers is a Mafia & such markets are only good for frequent outsider car dealers who are well acquainted with the art of making deals in minimum gain & are their regular customers.
My success in seling my last vehicle was through net site & the purchaser came all the way from karachi & both ends remained satisfied.
I am not against used car dealing business through car dealers but mostly are mannered , respectful , authentic & full of morality in between the deals , later they even don't own their receipts . Most used car dealers had the major jolt to their business through the purchases materialized through net sites directly between seller & the purchaser which they claim , but actually bigger jolt is given to the business by them for not materializing clean deals & through unrealistic tags to clean vehicles. Now , on even net sites most car dealers you will find portraying themselves either as seller or purchaser .
An advice would like to share for all those who wants to sell their vehicles is to be realistic & genuine about their vehicles worth condition & tag wise once placing demand advertisement & their patience till closest offer of meeting the demand will ultimately pay them . Because car dealer mafia also makes call through different names & depress the seller by quoting very unrealistic offers for a clean vehicle .
