If the basic premise of a Morgan is that they are, well, significantly flawed, and it's those very flaws that endear them to us, why is it so attractive to so many to tinker/fettle/engineer/weld/bend/wrench/adjust etc. in the pursuit of mitigating those flaws?
Personally, I don't see them as "significantly flawed" but I do see them as being considered 'primitive', in terms of elements of the engineering, and features, when compared to a similar vehicle you could purchase at the same time (and for the same price or less) from the 1990s forward. Perhaps I am being kind there but obviously, as time has moved on, the traditional Morgan has remained relatively the same, where as other car makers have killed off cars, overhauled them, introduced new ones and radically evolved them. The MX5 is often used as a comparable, as is the Porsche Boxster, less so the BMW Z3, Z4, etc.
Without wishing to go down the why a Morgan vs anything else debate, because that is well trodden, and ultimately, not the point of your thread, my personal belief is not only do people like to 'improve' but they also like to personalise.
To my mind, other than the old Land Rover Defender (pre-2016), there is no other vehicle that is more easily personalised than the Morgan. In fact, when buying new, there is no other vehicle that allows for such vast customisation without paying a much higher price point.
Thus, so much of the 'fettling' also falls into the personalisation category. From simple modifications like new steering wheels, to more extreme like entirely new dashboards, and then onto suspension and bodywork, each owner can tweak their Morgan to be exactly as they would like.
