Peter - I would agree with all of that. Particularly, buying a newer one, M3Ws excepted as I think they need more "hands on tinkering", means that you've a greater chance of jumping in the car and go for a drive rather than just trying to get it started!
For my part it's been jump in the car & turn the key & go over the first two years of Morgan ownership. Not quite sure that would have been the case I'd bought a 1960s classic.
