You haven't had much reply to this, - but it *is* also a rare car.
I have - on the other hand- had the pleasure of making a photosession of the second D'Jet in this country whatsoever (Denmark).
You can see a selection of the result here:

It is a very - very - pretty car, and I envy you.
Did you ever resolve the colour question ?
