Is the title "clean" or "salvage/rebuilt". That alone might explain the extent of damage.
I hit a deer with my Jetta last fall. To the naked eye, 1 hood, 1 fender, 1 bumper cap, 1 headlight, repaint areas.. well.. $3,000 later, it was repaired. I wouldn't have thought that much damage would have occured. My point is, it could have been a 5-7mph stop and go incident.. but fixing a Porsche won't be cheaper than a Jetta. Maybe you could track down the original police report to get an idea of what happened? Also, if the car is at a "highline" dealer, did the accident occur in their possession? Was the car bought at an auction? Maybe the titles been "washed".
Lots of questions imho. My guess is that if you wait 6mo, you could find a "non-stories" car for the same money
