Below some pictures showing the current situation (March 2020).
Right quarter panel:
Sub frame:
Rear "sand plate" completely missing probably sold when the car was scrapped as it is removed as a hole.
More rust:
I started by removing some of the few parts left on the car, rear trim and trunk lid hinges and some remains of cable harness.
The stainless steel trim I will try to reuse but some straightening out and polishing will be needed.
Attached four small temporary wheels to make it easier to move the "couch" around.
