Thank you! 
They could have left untouched, but... Lets see... I'll check a few other modification. They might suit. 
I didn't get any quote from Atlas. Looking at the amount of work, I am sure they would have asked above 100K for denting and painting; pus the number of days they would have spent on this car. Now, spending that much on this car wouldn't have been wise as the cost would have reached the market price of a clean 2004 City. Therefore, I went for my team of mechanics.
The painter is an experienced one and had worked at Vebra and Mak Motors in Islamabad. He was in working in Dubai before coming here. In this workshop, he is just doing my car.
The rear pillars have been treated just like any other part. The front ones are left as they didn't have any dent or scratches on them. However, they have been treated for the new paint.
Thanks for the wishes Daniyal Bhai.
