I suppose I should update this thread
The GoodWood ZS is still on the road, but has had no end of problems from the rear shunt, from leaking seals, to the new bootlid not opening or closing correctly.
So, since I have been offered a better base to start from, this car is being taken off the road within the next few weeks and stripped down. I will keep some bits myself in our unit and some bits have already been spoken for. But it all depends what I need to do to get the "new" ZS on the road again
(More on that in a new thread, once its on my drive).
