Still considering getting the wheels refurbished and would get them back to original MG ZT Apex Alloys spec which is Shadow Chrome (Rover Spec MBM). Not so many refurbishers are aware of the spec but apparently Chrome Shadow (BMW Spec A56) is very close.
They look very similar in the two pictures so that may be the way to go ……. they certainly look a lot better than the plain grey they are painted at the moment.
