As for the misting - I hear and understand the calls to accept it as a Morgan trait but it can't be right. This car with all the extras was about £52k. Add on the £8k of free kit from the 110 offer and it's £60k - There should not be an issue with anything costing that sort of money - and any niggles should be easily rectified.
Unfortunately this is an example of why it's best to think of a Morgan as a 1930s car that they forgot to stop making, rather than a modern car with a classic shape. They simply cannot be expected to have the same level of ergonomics, and I'm afraid it's not a question of money.
The problem is one of basic physics. The classic Morgan has a narrow engine bay with poor heat dissipation, and the addition of a modern powerful engine means there's a lot of heat gathering at the rear of the engine bay, soaking through to the under-dash area. The rear of the instruments is always going to be a warm place, and being an open car means the humidity level is always going to be the same as ambient, if not a little higher given there are human legs under there too, exuding water vapour.
The other factor is that the dashboard is hardly recessed at all, the doors are cut away like a proper roadster should be, and the windscreen is very thin with no A pillars to speak of. Thus there is no way for a pocket of warm air to gather and stabilise in front of the instruments.
So the inevitable happens: The instrument face cools as the car is driven, the comparatively warm moist air behind/inside the instruments meets this cold face, and condensation is the result. Because it's caused by the basic layout of the car, I can't see there's a way round it without changing the core design. Modern cars do it by double-glazing the instrument panel and having much more enclosed cockpits, but you can't do that in a trad Morgan
Many people have tried different solutions: increasing airflow through the instruments is probably the easiest, but it doesn't always work. Another way would be to somehow get the air inside the instruments completely dry and then to hermetically seal them, but I would think that would be almost impossible.
The best solution in my view really is to recalibrate one's thinking and learn to accept the characteristics of a wonderful car.
