insurance company not willing to replace rear bumper
As to not reporting an accident to your insurance company, if you read your policy, you have an affirmative obligation to report any accident you've been involved in (your fault or not). Not telling and having them find out later is what gets you the black mark or worse yet cancelled for violating the terms of your policy.
But, I was referring to the word "advocate." That has a legal connotation and Insurance carriers spend millions of bucks every year to get customers/potential customers to believe they have your best interests in mind. For straight property damage to your car, often your provider or the at-fault's provider will pay you about the same for "reasonable repairs."
Ultimately, the carrier will decide what is reasonable. This can work to your benefit or detriment, depending on the given facts.
You of course want to tell your own insurance company when you are in an accident, but that is not the same thing as filing a claim. Filing a claim usually will cost you a deductable fee, unless the at-fault driver was uninsured and in that case, many providers will waive the deductable. So, if you can just go through the at-fault driver's carrier, you can avoid the deductable, while still informing your carrier of the accident.
What you pay for insurance is relative to many factors and it doesn't change the fact that insurance carriers are in the business of making lots of money which will always take priority over pleasing their insureds. Put it to you like this: There will probably never be an occasion when an insurance company -- even your own carrier -- will spend more money than they legally have to in the handling of a claim.

But overll all the inputs you guys have put in here were just so informative for me and hopefully for others and will surely be very helpful for the future for anyone.
