I think they fit nicely, to the era that is.
You see at least in here many 300 were cars that elderly drove, for some odd reason elderly people did got those horrible things for their wheels and those do look pretty much what on that era 300 would had, so I think that it does indeed fit in and probably would pass even classic car MOT evaluation too, so can't critize very much.
Can't really see the horrifid uglyness some are seeing, sure I prefer looks without them, but putting 17" rims with 35 profile rubber would be a lot lot worse looking
