karachi parties import cars and our city dealers buy from them. they do not import directly as most of them claim in lahore.
you can buy a car from karachi from importers and bring it here. it will save you around 50-70k on one car as compared to lahore market. no need to go into auction and bid.
the other option is to keep checking when is the auction on the port going to take place. one can always try his luck there but a single individual has very less chances of wining an auction. mafias dont let you get into it. they pool together and sometimes buy a car higher than the market price but dont let you win
