Looks like a pretty decent van on the outside. You have something
special in that it appears to have been outfitted for the center seat.
If you lift the carpet you should see a couple of rails that a center
seat slides onto. That usually wasn't an option available on US vans,
so you might have a Canadian model (unless it was retrofitted by a
previous owner.)

You didn't have an pictures of the drivers side, so I can't tell for
sure.
