You can get a new Roadster in the States - MMC ships them to Morgan West without an engine and they then fit - think its a Mustang unit - this must allow them to bypass the rules.

Also nice 2010 SS on the Morgan West website.
Yep, that's the case. I've wondered the same thing RE: bringing the Aero over or at least the new Plus 8. My guess is they can't source the 4.8 BMW unit independently like they can the 3.7 from Ford. If they could, it would be just as easy to get a roller from MMC of their Aero's and do the final installation here.
