We just came back from a 7 day trip to Shogran, Naran, Babusar Top, Chilas, Gilgit, Hunza and Khunjerab top on BRV 2017 with 8 family members. During the trip we drove to Shogran 7750 ft, Duikar 10000 ft., babusar top 13690 ft, and Khunjerab Pass 15400 ft, we also have tough road from Chilas to Gilgit, we certainly have no issues whatsoever in travelling, whether going up or coming down. Very economical, comfortable and reasonable vehicle in this price.
Did drove back from Hunza to Islamabad in 13 hours constantly and no issues with driving seat too. Definitely recommended for middle class families who love to travel with leisure.
