When you say "Rolling Chassis", is it because in the states you can't buy a complete Morgan due to regulations, you must first buy a rolling chassis & then have the dealer fit the power train in the car?
You are correct, due to USA regulations, the only way around the red tape, is to purchase the "Rolling Chassis" and mate it with a factory engine and drivetrain in the USA. It requires quite a bit coordination and knowledge by the authorized dealer (MorganWest) to get it back to factory specification.
The end result, is just like when it rolls off the factory floor in Malvern.
I have wanted one for over 4 years, but never found one to my liking. So the opportunity came around, and moved on it with Dennis Glavis, who is quite an enthusiast of Morgans at MorganWest.
