I bought one. Its a little thinner than the factory rubber flooring. The fitment wasn't so good, it seemed a little loose in some areas. It looked like it could fit better with some work. I happened to find a nice used OEM rubber floor so I ended up not using the vinyl. If you go that route I recommend first trying to install it over the existing floor, maybe that would help with some of the looseness.
