The doors were OK(ish) the bezel round the door release on the driver's side was broken, the vinyl on the door itself was unpeeling & there was an MDF trim panel screwed - sort of - inside that.register. I also replaced the hidden but ugly bolts with titanium ones as they'll now be on show.
The next job was to cover the inner door face with new vinyl & punch through where the holes were & re-fit the door. It now doesn't need the trim panel at all, that tipped the scales at 1kg, so when I've done the other side, that'll be 3kg of mass lost in the door alone (with more to come when the heavy stainless side window supports go). Total mass reduced on the car is now 9.5kg or 21lb in old money. In the photo below the clamps are still in place while the glue cures.
Also yesterday I took the seats out & mounted them by all four mountings as they were only attached by the front two mounts which made them a little wobbly.
Every day the car gets a little better.
