Do these two sentences need to be hyphenated? It seems to me that "ever" doesn't really act as an adjective to "car," but I could be wrong.
"That was my first-ever car."
"She's the second-best writer I know."
My research show both the "first ever" and "first-ever," but it doesn't say if it's style. If anyone is more familiar with hyphens, I would like this to get claraffied.
