Visibility is average in the 2007 Nissan Sentra, even with large exterior mirrors and plenty of side glass so as to make over-the-shoulder viewing worry-free. Those are the highlights. Among the issues that require some attention are the thick A pillars that limit the front quarter view, a short rear window that is handicapped by significant outboard headrests (though they do tilt down), and the teardrop shape of those outside mirrors – they pinch at the outer edges and create blind spots.
