Mateo can't comment on US ownership but maybe as a true petrolhead you were born the wrong side of the pond. My experience of US cars is based on holiday rentals and thy all only seemed to like going in straight lines.
Are there some major drawbacks I don't know about?
Having to explain what it is.
What I can't fathom is why Aero8s aren't more popular. They seemingly sit unsold on dealer lots for months on end, at the price of a used 911 or Jag XK.
My guess would be the size of the marketing budgets of both.
In my opinion, with a good power to weight ratio, sweet drivetrain, cool heritage, and rarity they, should be on every petrol head's "must have" list. So what is the problem? It all seems to good to be true.
This isnt just a US problem, I went on a run a few years back and a guy in a new R8 had assumed the aero wasn't capable of much, He was rather upset that I'd sat with him every time he tried to pull away, he considered himself knowledgable and a petrol head. The reasons they don't get it are all the reasons we do.
ps. what's the average age around here? I can't seem to find anyone my age that even knows what a Morgan is

then again I'm a real car nut.
Physical or mental age?
