Yes, it did indeed look like a nasty accident - but it wasn't Morgan, and it was also a comparatively old car, so could well have been caused by a component failure - something to which a modern Morgan would not be exposed in the same way.
Given that the components most likely to fail and cause an accident are the old style running gear rather than the engine, I cant see that, but I have to agree 100% with the rest of what you say.
