Several items of interior trim were missing and the glovebox had the "carbon fibre look" finish to it. Interior was very dark indeed.

Mike at LotusBits helped me out and I now have wood effect door trims, glovebox and inserts on the transmission tunnel.

It really is no wonder these cars turned out so expensive to make. The man hours in each one must have been huge. Just to assemble a door must have taken a fair while. The wood effect door trim is made of thin steel with wood effect coating. Then a flimsy alloy trim is clipped on all around the outer edge and held in place with tape on the back. There are then about 6 projecting bolt threads on rear surface that have to be fed through holes in the inner door skin. A washer and nyloc nut is carefully done up on the back surface on all 6, two more hold the ash tray assembly in place.

The glovebox lid comes as two parts: the base of the glovebox and the flip down lid hinged at the bottom to the baseplate. To fit the lid you actually bolt the baseplate down in position with 4 small nuts on underside. This means doing it by touch or lying face up in the footwell to get the nuts on.

I could not find a replacement wooden ball gearknob of the type originally used. They tend to have rotted away on all old cars and none of the specialist suppliers had any in stock.
In the end I had to get one for the huge sum of £2 on ebay from a US Truck accessories store. Tapped the thread on the metal insert to fit and applied 3 coats of varnish.

That's better!
