I think that the days of 'hand built' went some years ago. It's very much 'hand assembled' nowadays.
I can't imagine that there's much scope for artisan flair in the construction process today, there has to be standardisation in the assembly process to do away with friday afternoon cars and variable build quality.
If the Italians are asking £100k+ for the plus six then, at that level, and with the expectations of the clientele, there is no room for the 'quality fluctuations' of a hand built Morgan........🤷🏻♂️
