It also could have given way because the owner didn't take care of the car as a whole and ran it into the ground.
An engine can be rebuilt, but condition of the rest of the car is hard to replace.
The rear upper trim have the same fault as most other peoples, the material is starting to pull away from the plastic.
I can take some pics of them when the weather is clear.
Generally speaking from my experience the blown engine gtr's are also very used in all other aspects too so whilst you might get it for a low price the quality of the interior and exterior will also match that price.
I killed approx $20k at WSID in my mess and even had the tow truck driver spinning a story for my insurance claim, why bother though just take it on the chin and get on with life.
That Territory is down to an 11.1sec pass.
And that is a lot of damage for the speed that the GTR backed into the wall, so as Chris Easton says - Say No To Concrete!!
