The 3 wheeler is basically assembled by morgan, i believe. I know they make the ash frame. Do they make anything else?
The three wheeler is a much more standardised assembly than the 4 wheelers. The ash frame is really only a token to Morgan tradition and the car could have been built just as easily with another type of frame, as the several Not-a-Morgan 3 wheelers have shown.
The ash frame, however, does have an advantage in light weight, strength and resilience.
