A small vocabulary spoken well is far better than a large vocabulary spoken poorly. I think that is one reason why the Dutch (and Scandinavians) come across as so fluent. Have to say I'm impressed by the idioms they come up with though, presumably from the same American TV shows with otherwise small vocabulary.
In support of your theory, the extreme example would be Donald Trump who has a small vocabulary used spectacularly poorly!
OK, back to the fascinating discussion of floor mat fit.
