Right, it's been a while so I better crack on with this!
Next up I'll be removing the headlining to re-cover it - it's started to sag at the back.
The fix to the sunroof drains using our kit (here:
https://bit.ly/2Xazc7w ) seems to have done the trick - the interior is now bone-dry.
I've done various other bits and pieces (I'll come back to list later) and she's slowly getting there - next up will be an MOT after some careful checking over.
