Other than the upgraded sound system (12 or 18 speaker) and the trunk carpet and hood liner is there any other difference between a standard ACR and a GTC ACR (exterior/interior package with CCB)? I think the standard might come with a lithium battery and the GTC maybe has some additional sound deadening material in the cabin (thicker/heavier carpet I think).
I just got my GTC ACR and love it. I'm asking this question just because I'm curious.
