I was given a P85+ loaner and noticed that the interior lighting (dome lights, etc.) and trunk lighting was LED. Was this a standard feature or option for the P85+? Or did the SC upgrade the lighting? I don't have any first hand experience with any of the MS variants prior to the P85D so excuse my lack of knowledge. I was just surprised that the premium interior package on our D didn't even come with this. Looks a lot better.
