Guys I own this car. Let me give you my findings about the door. There is no issue with the door quality as the doors are pretty solid with safety beams in it. The only thing is that they sound different while opening and closing for which according to my findings is the latch. I took it to mechanic who specializes in door adjustment and dress-up, he just adjusted the door latch and striker and the sound of the door changed. He also recommended to put an additional door weather strip on the body where the door touches the body frame. I will update once I find some time to make that change.
Besides that the car is performing awesomely and fuel average is getting better day by day as Mr. Mohsan also mentioned. The body is solid. My friend has a 2009 Vitz and I compared the Dashboard material with V2 and it was exactly the same except the the dashboard textures were different.
