Importer and dealer are 2 different things. Dealer and Importer can be same person, but 2 different persons too. An importer cannot necessarily be a cars dealer too and having his cars showroom. He can just work as a facilitator, and having his some profit (which may be marginal, but worth his efforts and hassles).
Thoray sey paisay dey dein, kuj nai jata Jahan aap 20-25 lac PKR (or may be even more) ki car import Kar rahay hoon, wahan 20-40,000 PKR (depending on car's price) chubhnay nai chaheye! At least you will have complete control and guarantee of everything!
