I appreciate the advice. The problem is not that I believe the estimate is too high - I'm sure bumpers are pricey, but he doesn't need a new bumper! There is no dent, nor is there any break in the surface of his paint. It can clearly be buffed out.
Out of principle I can't pay this guy $1,800+. Would I be better then to let him sue or go through the insurance? Or does that open up a whole new can of worms? I guess in essence he could show me a bill for $10,000.00 - where does realistic end and scam begin? Can I not protect against this in any way?
He'll probably just keep the money and get his bumper buffed anyways.
