Although relatively new to Morgan ownership (2+ years), I've noticed that MMC update specs (and price!) of new cars to include items that were previously extra cost options. Before this happens its possible to nearly double the base cost if all options are added.
The latest Euro 4 spec M3W's are a special case given the range of changes made to comply. KH had a new one in with their own special matt black paint job for £49,000

- amazingly it was soon sold.
