The very inaccurate science of counting US M3W Vin registrations on this site, scrubbing Morgan club memberships and speaking with a number of Morgan dealers would suggest there maybe as many as 230 (+/-10%) M3W's in the US as of late summer 2016. This seems realistic if you consider the 13 or so dealers in the US, 3 of whom have told me they've sold between 12 and 32 with about 10% being shipped back out of the country.

Then again I could be wrong, and usually am!
