@saboor73 cool down, u r sitting on an open forum so respect other members opinion and enjoy 
Now Coming back to the Question Why Liana Failed and Swift rocked. here they r
. Liana was launched in 2006 to meet the sedan category of Shuzuki. When the car got launched, people took great interest in it. But when people bought it and the car gave serious problems, its market started detoriating, and sooner the car got flopped. Suzuki rectified those problems and launched Vurv but it was too late,
Now why swift rocked.?
Swift was launched at a time when Pakistan badly needed a powerful hatchback, So Swift became a big hit, The Cars looks were stunning and was real attractive. and this time build quality and standard was the top priority, the ECU was programmed properly and the engine recieved different types of alterations and the suspension of Swift and Liana is certainly not same, Liana is softer while swift is harder similar to current gen City, So it became a hit.
As Far as Mira E;S is concerned, Who said that its a hit, the car is performing poorly in the market, But the reason for cheap plastic is that the car is made light to reduce weight and save fuel, even the latest gen Passo and Vitz r having the same type dashboard but the finishing is still 100 times better than paki, but yes Mira is a fragile car.
As Far as resale and market is concerned we Pakistanis r not rich to risk our money like Japanese and Europeans who use the car and throw them away, A person who changes his car every year and has a medium salary will definatly look for resale and mechanics
Chill out bro,u like liana its good but not everyone has the same choice.
Peace.
