I would say yes, that is accident damage. However it is minor and can be easily repaired by any competent body/frame guy. I used to be in the business and have worked on at least a hundred wrecked/totaled Pcars. I doubt it is affecting the driveability of the car but I would probably get it repaired. The best way to confirm is to take measurement as suggested to make sure everything is square.

That sheet does make it seem a bit simple to just get home and measure.

To me, globally speaking, the car is actually indeed bent at the rear. The rear of the car is sort of bend down and that is what you can see in the pictures I posted last year (or the year before? ) But my point in even continuing and not just scraping it is this:

1) Its an 86.5
2) I scrubed the whole car.
3) I put a new windshield in before I saw this
4) I welded the sunroof and added headroom
5) It can simply be a throw a way car with the pieces I am using. Fast, but throw away.

I don't think that it affected the main shape of the suspension mounting points. I just think that main rail behind the shock tower is bent down. Shortening the opening length of the fender well opening.

If its like 500 bucks to have someone straighten it, I would. If its 1000, not so much.

On that note, I'd take Jerry's long distance diagnosis with a grain of salt, he's been wrong before.
Its isolated. But its bent. I will take more measurements and post back. I mean if I can find that the diagonal distortion is measurable from front to rear of the car, Its junk.

Damage that far back is pretty much cosmetic only...pointless to spend much fixing it now. Just drive it and maybe someone will rearend it and then you can fix it or if these cars get really valuable get it fixed THEN.....just pretend you never looked at it

BC, the concept I was trying to convey is that poor hatch alignment is the canary in the coal mine, so to speak.

Given the monoque construction it's very difficult to alter any of those datums without the entire monoque being slightly 'sprung' out of shape, including the roofline.

Given the position of the hatch hinges at the rear of the roof, even the slightest up/down front/rear or side-to-side change is magnified by the length of the hatch an will show as a mismatch between the corners of the hatch and the pointed corners of the bodywork, so slowly lower the hatch to the closing point to check. Front-to back mismatch indicates a hard nose or tail impact.

Sometimes it's possible to correct slight misalignment by shimming the hinges, so check for that.

You'll look at a lot of cars before you find one of that age with such good hatch alignment.

HTH.

BC, it's not without basis, let me assure you.

Buy a toy car, say shoebox size, 2-door preferably. Then glue a pice of plastic/stiff cardboard on the rear of the roof in the same position as the hatch.

Twist or bend the car and observe the bottom end of the 'hatch'.

Oh, remove any sort of hatch or infill on the model car first, so to mirror as closely as possible the 928 situation.

V.interested to hear the result.


Cheers

Brendan ... All the crossways lines of measurement should be parallel, so you can take more diagonals, and measurements from the end of one to the end of the next, to narrow down where the problem lies.

From a known undamaged area such as the line between two holes F, you can take measurements to the end of lines G, H & I on each side, and throw in all the diagonals you like and it should clearly show exactly what's happened.

It may be much more simple to fix than you think. Apply the right pressure at the right point, and even if it's been bent down, you should be able to get it back to the right dimensions.

Once you know what's happened, you can apply the reverse of the force that got it to where it is now, to get it back where it should be ... all is not lost
