How does this work? Do I call the dealer?

Call them or better yet, drive there and take a look in person.

Well, there's no way to do that since the name of the dealer is not provided. This answer is not helpful at all. It turns out that the only way to contact the dealer is to submit a "request information" .

If a dealer won't give their name then they probably are not worth doing business with. One trick is to "google" the VIN which will show up all the ads for this car on the net.
