somewhere on the WEB there is an article - i think from Cranford college that says that a Morgan is as green as a Toyota Pious because of the green way they are made.
I am sure that the old "Salty Sea Dog" will remember it.
I remember that article (virtually) in the Centenary year and the Smart for 2 came out top.
It was the year I swapped my +8 for the Sport.
Here's the link - refreshing to find not all the brain cells have died
