Luca, your opinions, and feelings expressed are absolutely valid and have been shared by many here over the years (myself included), although most have likely stopped reading/posting on TM because they have moved on for these same reasons.
My frustrations were from dealing with Morgan's senior leadership, and not a dealer, around my own service issues and their associated apathy. That past is well documented in many old threads here, with a little searching, so I’ll not dredge more.
I agree that hearing, "they all do that" or, "that's [breaking down] part of the experience" should not go unquestioned either (Stockholm Syndrome?).
I'll also guess that you're in California from my own experience in dealing with a Morgan dealer there.
By the time I sold my M3W each mile I was able to drive in it cost me over $200us. The saying 'in for a pence, in for a pound' kept resonating as the invoices accrued, as was the irony of the saying’s origin; eventually I 'cut bait' (to use a different saying).
I'll also admit that if I was not able to find an ACE 3-wheeler, I may even still own that M3W.
Good luck Luca, with whatever path you take...
