These the last few cars I've owned or driven/ridden in regularly:

Toyota Highlander (my current car) - definitely seats five. Seats seven, actually. but I frequently have stuff in the back so the third row stays down unless necessary. The second row has a middle portion that's exchangeable. It starts with a full seat that folds down into an arm rest. When I don't want the seat and want to make it easy to climb in the third row, I take the middle seat out and stow it away under the center console in front, where a tray comes out and goes where the seat was. It's a little weird to explain.

Honda CRV - my wife's car. For a tiny SUV, it has plenty of nice features, and easily seats five. I'm a big fan of it, and it's a heck of a value.

Honda Odyssey - my last vehicle. Loved it. Again, that sat seven, and a full seven.

Now the less helpful...

Mitsubishi Eclipse - did that have a back seat?
