Thank you for your valuable input....
In the article i tried to highlight the issues that spoiled the repute of the car at the onset. As of now, most of the issues like technicians training and availability of equipment have already been addressed, but my point was that 'damage was done' before that.
Regarding stability, the point is only while "Turning at high speed", otherwise Liana is quite smooth in straight drive (as I have even seen a video by someone driving at 195 KM/h).
Quality of material greatly depend on the usage conditions, i opined on the basis of most of the cars on the road, definitely with good care, the life of materials improve. (like you have kept your car)
Anyways thanks again for your comments.
