It has to be said that any trad Morgan is never going to 'just work' without a certain amount of active owner involvement. These cars are not like other modern vehicles, they can't be treated like them. The Aero models may well be different, I have no experience of owning one.
The front suspension on a traditional Morgan needs to be greased every thousand miles or so for example, and there are plenty of nuts and bolts and other fasteners that require checking. The rear springs needs a quick spray with lubricant every year or so. Wire wheels need to have their spokes checked. None of the regular maintenance jobs are difficult or onerous, none of them require special tools, but without them no trad Morgan will thrive and give of its best. Personally I love this, it makes the relationship with the car much more fulfilling.
I expect it may be possible, with the help of a very good dealer, to run a trad Morgan successfully without ever getting one's hands dirty, but I wouldn't honestly recommend it - if for no other reason than it prevents you from being able to go on an extended tour of more than a couple of thousand miles without worry.
