I'm trying to think of words to describe that barnacle on the back of the car.
My immediate thought was 'greenhouse' but missing the glass. To my eyes, it looks like the miniature greenhouses used for cuttings and small plants.
However, saying that, at least it is being marketed... my car has been at a dealers, along with another owners, for over four weeks and yet neither Morgan is yet to even be listed on the dealers site.
