I'm going to have my car transported from Islamabad to Karachi in the coming few weeks. Which service should I go for and how much should it cost?

I have two options right now - Muslim Car Carrier and Asif Car Carrier. I don't know anything about their record and how they handle cars. I don't want my car to come back to Karachi scratched and dented.

Has anyone had any experience with any car carrier service? What are the dos and don'ts here?
