He ll say u for registration. If u agree for sindh registration, which u ll definitely not to, ask him that u ll deposit security amount and will get it once u get the car registered. I also did the same because i wanted to have islamabad registration. If u need my help, PM me your number i ll call you or i can even talk to that guy. Moreover, he issued me PBO right away so that was a sigh of relief
