Big car?...
I am assuming that the new M3W will not share the exact same chassis as the plus 4 and plus 6, but will be much smaller. Bear in mind that the CX designation was applied to the new type of aluminium construction to recognise Morgan’s 110 years in business. I would guess any size of Morgan chassis designed on similar principles and made from bonded aluminium would fall under the generic umbrella of “CX”.
