I hope the new frame is not for the 4/4 and +4. For me, a real Morgan is a new built vintage car with a modern engine and gearbox. With ladder-frame (same design since 1936), leafspring suspension, kingpings, wooden body frame, slim coachwork.
So the new +8, or this new roadster is not a real Morgan for me in the same way a Porsche Cayenne is not a real Porsche.
