I offered to sell my car for 2.5million first, but he didn't accept it. he said he will pay after the exchange. i didn't know about this tax thing.

Guy is scammed me with a car exchange. he said we exchange cars then he pays 2.5million. then i was honest and said since theres no drift kit on the car he can pay 2million except 2.5million, then he can buy a drift kit to it. then when we were on the way to the bank he dropped me out of the car
