Look at the Quest's expansive wrap-around greenhouse and you'll think that visibility is terrific. Indeed, the side glass is long, side mirrors appear ample, and the windshield is enormous. However, when the driver looks over her right shoulder, the second row headrests block the view, and the rear headrests eat up a big chunk of the rear window. Thankfully, a pull of the strap on the back of the third-row bench folds those noggin supports easily. Outside, the beltline gradually rides, making it hard to see cars traveling next to the rear passenger side, while the driver's mirror allows for a blind spot when cars are close on the left. The optional rearview camera is a huge help when backing up.
