when i was searching for liana in 2013, my uncle, who is a car dealer, adviced me never to buy a ff cng kit liana...same thing was said by all showroom owners at jamshed road (as i had an extensive search). i saw 3 to 4 cars thru Dawn paper and all owners said that same...those who had the ff cng installed at that time offered us a waiver of 15k for the kit change or promised to strike the deal once they themselves will have it out..
it was very funny for me always when almost all liana owners and car dealers said exactly same for ff cng kit...
