I remember I bought a fresh import 2015 Aqua (brilliant car) it was my first time buying an unregistered JDM car.
After finalizing car, negotiating price getting its autction sheet verified, pakwheels inspected , gave token amount and told seller to come to excise office with me tommorow to submit its file (JDM cars have a file with 12-13 documents).
I told the gentleman you can verify my payorder from bank branch of your choice but If and when all documents plus physical inspection of car is cleared from excise only then i'll hand over the payorder , As expected was faced with some resistance but as I was willing to walk away unless he agreed , the seller did exactly as I wanted, car was registered without any issue and payorder was handed to him.
I feel like you can get scammed only if you are in a hurry for whatever reason or just being blinded by greed (too good of a deal to be true )
