- is cng easily available throughout this route i.e. khi-psh??? i would most likely be touching entire punjab as well and will enter NWFP through isb.
bhai CNG is easily available from Khi to Peshawar:D only at super highway ( Khi to hyd) its not availabe but after crossing superhighway u'll see CNG stations after every 20 to 25 Kms.
if u go towards northern areas then the last CNG station availabe is at Mansehra. after Mansehra CNG is not availabe
- wats the road condition overall? i mean to say, if its ok to take a "car" or jeep would be a better option?
bhai road conditions r fine n corolla can easily go:D i took my corolla to khunjerab in 2004 in 2005 kaghan, swat u can hire jeeps from there ( particular place in Northern areas) n if u have a 4x4 then the decision to take 4x4 depends upon ur destination
- r u satisfied with corolla's performance on such terrain/long routes??? i am planning to take my xli along.
