Al:
My recollection from "back in the day" as they say was that the interior panels were a gloss finish. By todays standards probably would be a semi gloss. I don't remember ever seeing a car looking like they can today with these new paints. I've been around really nice single lacquer paint jobs back then that were really nice but not like these two and three stage paint jobs of today. So my two cents is "sort of glossy".
