First of all there no comparison of material used in Liana with any other car of suzuki, pak made.it is far better. I have run it till 1000 km yet, on patrol only. pick, gear shifting is awsome. i got problem in from light beam, i mean light level is disturbed, while in full beam its quite good. interior is far better than city or any other 1300 cc.Sound system is good, with 4 speakers and mp3 players. i got no problem in any part of the car as i m going to have its FFI this sunday or monday. CNG-Patrol conversion is very very smooth. there is only a little jerk in the race when u on the A/C while driving below 40. other wise no problem in pick or something like that. CNG Arrangement is quite good. as well i have heard that honda will not claim any warranty if you install CNG in its new purchased city or civic. I will always prefere liana over anyother car, not only for this reason that i have it, but i m CNG user and i dont have anyother option which is as best as Liana in its price. decision is upto u.
