To me it looks more like a selection of parts, there doesn't appear to be a chassis.. Given the uncrumpled state of the fronts wing etc, it doesn't appear to of been a accident..
Maybe a restoration was started but never finished..
The wheels would suggest 82-92, however they would of fitted on any earlier morgan, as they are just VW ones quite easy to get hold off, however headlight pod position means it must be post 1969..
