I am likely to risk offending someone but you are comparing a car made by a car maker with a lash up kit car. Admittedly the original 1960s AC Cobra were just that - shoehorning an big lazy american V8 into an antiquated British sports car chassis but over the years they were developed. Still crude but developed crude.
I guess as a Morgan owner you are used to tinkering to get things right or at least righter so you might be happy with a kit car, but in the rain? Going any distance? In ( god forbid) a crash?
