Your clutch should be new (or little used) and check your brakes also.I would advise you (depending upon your car) to limit your visit to Murree only.
If you go to Nathia gali or ayubia, there is too much incline and decline in a lot of places.
Same thing if you want to go to Naran, then Balakot will the difficult area for you as there is too much incline and decline in this part
