Liana and Swift or even Jimny had the same m13a engine. So if ustaads were not willing to fix lianas how are Swifts and Jimnys running good.
So its not only the engine that was wrong with Suzuki Liana. Out of all 3 Liana is the only car to lessen engine coolant levels.
Even if you like the 6.75 lack liana make sure its not a CNG driven car. Petrol variants of Liana have been soberly better. CNG variant is out of the question.
As other people also mention suzukis made before WagonR and new Cultus or new Alto had pathetic quality of plastics, door handles, wiper, coolant bottle caps.
Newer ones are still not par but better.
Suzuki Swift does feel premium when you sit in it after sitting in any other local assembled hatchbacks. But Swift has one of the worst cushioned seats ever made in a Pakistani assembled car.
