After speaking to various US dealerships about the issues with my M3W, there was a common thread among them. Morgan does not allow enough reimbursed repair time for a proper repair and therefore, the dealerships, understandably, don't won't to go that route as it is a money losing proposition for them before they ever turn the first bolt. For example, I was told that Morgan only allows 8 hours shop time on a compensator swap and that several competent mechanics (some of which provide service on other high-end European sports cars) are seeing three times the hours for the swap. No matter how much sympathy the dealerships have for you, they can't afford to absorb Morgan's responsibilities.

When my old one went back to the factory end of last year I was told that the dealers were allowed 12 hours for the compensator, with practice / experience

the factory may have got it down to 8 hours. If the dealers couldn't do it in that time then they were more than welcome to attend the factory to be shown how to do it.
I know not that practical for overseas. Surely though a training web seminar could be setup or even a video to help the oversea's dealers resolve the technical difficulties they are having in repairing the cars within the allocated time given for warranty items. Also manufacturers never give the total time, it always has been trimmed in their favour.
