First, I'll reply to you with some personal anecdotal stuff. I have a truck, very unmustachian. A year ago I backed into a car when we both were pulling out of spaces in the parking lot. The dent is moderate. Not huge but not small either. Only recently I started thinking, I have some extra money, maybe I'll get it fixed. I got a few quotes, each around 1000 for everything included. Personally, I'd guess that if you quoted the exact same price people would get at the bigger chains (Service King) along with the added convenience of doing it at their home/work (maybe even at night or on the weekends so they wouldn't miss work), they would be all over that. I would guess that you know prices better than me; talk to estimators you know from the old job. Another factor is that my price is for a truck's steel bumper (collision places claim that they can't repair a steel bumper), so I'm guessing the plastic bumpers for cars/SUVs are cheaper.
Second, I'll ask if OP or anyone has any suggestions for my personal situation after reading the above :) My dad is handy and works on his old cars so I thought about buying a bumper and replacing it ourselves over a curse-filled weekend. However, the part itself would still be ~500 for a chrome (not matching my truck's color) bumper. I came to a revelation when my gf said "it doesn't really look that bad to spend ~1k." Wow...yes, she's a keeper. I've settled with how it looks for now and trying to learn to just be ok with things that are suboptimal in an effort to save money toward my FU fund. I guess I would still think about fixing it but only if the cost made sense. Plus, there's the very real possibility that I would fix it and then promptly f*** it up again soon thereafter. Or more likely, someone would rear-end me. God knows it's just a matter of time until karma catches up with me in the form of someone hitting me. In which case, fixing my bumper would then be on their dime, with their insurance :D
