It's not at all a matter of harboring the price, but my costs can't translate well to another's repairs based on so many variables - location, area competition, severity and accessibility of damage. I can tell you I estimated labor hours x normal shoprate, a little for special tool costs and some shop o/h, and came up with my own guess. Then, I went to a place recommended by a trusted bodyman and was quoted right at twice that amount. For a check I drove to a closer location (and different franchise) that does this work along with quite a bit of other one-off exotic car stuff (new Aston Martin getting entire nose clear-bra, Ferrari getting exhaust). An intelligent professional sounding fella gave me a quote ("maximum $XXX, could be less") which was 2/3 of the first quote, and ended up paying a little less than the max and within $25 of my first guess.
The biggest factors at both places mentioned as critical are depth of ding (stretching metal), sharp creases (can crack the metal and/or paint when doing the work), ease of accessing from the back (mine were obviously easy), and anytime damage gets below the color (which in my case was "real close"). BTW, it was almost a 1/3 of the insurance estimated doing more customary bodywork/repaint - including my collision deductible.
Do your own guess and just call and let a couple places look at it. The more stuff you have done at once likely the most economical eh. I have a few door dings on my black car, and figure I'll go back to that place for a quote and offer to pull off the panels myself for a little savings. Good luck.
