Put my Weathertech floor liners in today. I love 'em. They're not quite as snug as I'd imagined, but snug enough that I'm confident they'll stay where they're supposed to. Seem reasonably sturdy, well-designed, and attractive, at least as these things go. Even the wife likes 'em--always a plus!
Edit: And yes, the rears fit just as nicely as do the front liners.
