I noticed water inside door after wash? Is it normal?
Yes. Totally normal
They just sprayed the water outside of the car, they didn't wash car by opening the door at all, it is when I opened to door to drive noticed it.
What worries me is that, it is the same area that has door latch, light on off button.
Whats going on with the plastic on the finished seat areas?
This is normal.Dont wash your car too often and it will not catch rust for years.
Wash it unless you drive it in rain or extremely dirty. Maybe once in 6 months a full underbody wash. Thats it.
I see drivers giving ghussal to cars everyday 365 days of the year. Absolute madness.
You forgot the part where they love getting that underside coated with old brake oil or engine oil. Cuz Fraaaaash look sir ji.
O Yes. suspension naram aur shaiin b ajati hai.
