You are very right, actually the parts pak suzuki are using are of very low quality.
The parts they are using are already rusted.
I have a experience of using a cultus , once the door get hitted and got very light dent. When i went to get it repaired and the denter opened it from inside. ( Dalda ) was printed inside and it has also rust from inside.
Seems like that have used some old sheets from old dalda recycle oil cans..
Sooo heart breaking........
Similar cases from lot of mehran also..
