Hi Pete
I moved over!
My Morgan journey started with the M3W - I had wanted one since being 9 years old!
After two years and too many issues I changed to a 4/4.
It was a radical change. The 4/4 being very different driving experience. But a positive one. There really is no comparison between the two.
As you say the 4/4 is maybe more usable - having a heater and a hood!
More space and sidesceens!
I then had a Roadster for 18 months and now just in the past month a 4/4 80th - so have gone full circle.
I really do like the 80th! Packed with goodies and differences from a standard 4/4 IMO.
Good luck whichever way you decide to go.
