Car hire in Pakistan- one way rental charge
 

Hi there,
I'm looking to rent a car for a road trip in Pakistan. I'm picking the car up in Lahore, and dropping off in Sost. From the research I've carried out thus far, this would almost certainly incur a one-way (drop off) charge of approximately $1000 (differs from company to company).
The booking would be with the company Vertical Explorers. Has anyone else had any experience booking with them? Have you had to pay any additional one-way charges when collecting the car?
