own ? to own a car you need to spend money? does OWN mean in your question as Premium Price ? for immediate delivery?
remember you paid withholding tax as well - and any buyer who will be buying it at premium price will be paying withholding tax in addition to premium and you will get notice from FBR in 90 days for income tax returns. because withholding tax paid under your CNIC is reported to FBR by the manufacturer.
