My GPs have had multiple totals but all have kept clean titles because I kept the "salvage". I even have full coverage on one that had a hit like the car you are looking at. Its my daily driver but I fully repaired it. Until it was fully repaired, liability insurance was all thats allowed.
"Structural damage" is a term that creates less confusion when talking about subframe cars. There are those who insist that a frame is only a frame if its full length and seperate from the body. I'm a bodyman and can promise you that every car has a frame. With unibodies and subframes, some of it does not unbolt. Trucks are whats called "body-on-frame". W-bodies are "subframe cars", they have one front and rear. What I call a unibody would be like a Fox Mustang, where the only part that unbolts is the one with the engine mounts and steering rack attached to a tiny crossmember that does not absorb impact from collisions. GP subframes are definitely part of the impact-absorbing structure.
