Well, wagon got hit need qtr panel.....

Myself I would get the estimate on having the job fixed by a pro. Get three in fact. That is a very repairable dent. Once that main damaged area is pulled the rest for the most part will kind of repair themselves as the larger dents around the main one are being held in place by the main dent. A good body guy would have this dent out in no time. You might be opening up a whole can of worms you dont want sectioning in a partial panel. If anything is not done right cracking, popping filler from pinholes or gaps in welds, warps in the panel from too much weld heat etc may be a constant problem down the line. The panel to me looks to be a straight forward job. Spot welded or 'tacked' pices of matal tabs with center holes put in the center and sides of the main dent and a large dent puller will bring 80% plus of this dent out in a heartbeat. Then some time with some dollies and a couple of different shaped hammers and this dent is gone away with just a skim of light filler. Not my car but I would repair rather than replace any day.
