my dealer says that ARP4 comes with standard Morgan steering wheel (not sure what this is, but it isn't the one in the press pics)
the alcantara steering wheel with the yellow marker is the optional extra cost removable steering wheel
makes sense because there is no mention anywhere of the alcantara wheel being standard (they list new sound system, fancy wheels, new dash, ali door panels etc, so I would expect them to list the alcantara steering wheel too).
further, the press shots of the car show lots of cost options such as red calipers, gloss paint, rear tonneau cover, front spot lights, gloss black wheels
