I have seen a place that does wraps and after seeing the job they carried out on a BMW Z4 I had thought of having just the roof panel done too, same style as the original Volts. I don't know the cost yet, my only apprehension is that with another set of photographs they have one showing the roof lining dropped in order to remove the aerial to get a good finish. At least if you get a vinyl wrap it can be removed prior to selling on with no damage at all.
