Replaced suspension parts due to being bent smells of someone slamming the rear of that car upside a curb...
Walk away from this car for what you don't know about it and what you may not be able to find out no matter how hard you dig.
There's a couple hundred quality examples of 05 987S's out there at any one time and you should find one that has a repair record that is bent-part replacement-free.
Best of luck on your hunt! One day I'll hunt for an 05 987S myself
