Why the heck number 3 still applies.... zzz warranty?

The sorento was the victim. Either he pays, or claim the insurance of the offender.

and it's not about hassle... If it's your new car you want to just go through normal outside workshop paint job with no guarantee watsoever it won't fall off the moment you drive out the next day?

This is about right and wrong. YOu bump into someone. YOu're responsible for the damages. If the victim cincai, then ok. If the victim go SC and SC says want change whole body side panel. Still your fault and your responsibility. Ain't no ketuk ketuk for a new car. And expensive car somemore....

personally i will go through the hassle, i dont want lousy paint job
and since he pissed me i will piss him back double

yea some ppl dont care their car outlook much, just a transport to them
while some ppl one hairline scratch cannot sleep until it is fixed
