Where can one get a supersport , presume its a hens teeth situation ?
If you are serious... Get to know a number of Morgan dealers, and let them know you are in the market. They will know owners who may be potential sellers at the right price. It took me a year of 'stalking' in this way to find my Aeromax. I was prepared to be patient and I really enjoyed getting to know a handful of dealers who were, without exception, lovely people and one of whom came up trumps.
