The 2007 1800 duratec 4/4 we had averaged 45mpg over the year we had it based on odo readings.
The Roadster 100 is averaging 29mpg so far with 31mpg over the best measured period.
The heavier 3 ltr S type V6 automatic with aircon is at 25mpg over 12.5k miles so I think the Morgans win on running costs hands down.
