That's the actual reason you just mentioned is for using own car, plus I will have confidence on my own car with family than a rental car.
Transit time they commit is 3 days but maximum they take 5 days. I will give them 5 days before. I have never transported my car ever but a colleague travel alot between Islamabad & Karachi using this option with family and his experience is so far good within 5 years.
