I think RM700 is fair, cheap even if he want to get the entire panel replaced by the authorized SC, which is what I would do anyway if I am the victim. Why should I settle for a lousy ketuk ketuk job for new car because of someone's fault.

Without picture very hard to tell, and even if there are pictures, they may not tell the whole story. There may be some internal damages like clips etc that needed repair or replacement too.

But best thing to do is, if the victim wanted to get it fixed at the service center, follow him and get the quote, then that will make sure you won't be taken advantage of.

What happened to your bonnet? Did it involved with knocking? Replacing the entire bonnet?

Well..If no knocking or panel replacement then 500+ for the paint job is fair considering you did it in the service center.
