I like the cooling exhausts just behind and above the front wheels (though a web site says they are non-functional), the shape of the rear roof, the location of the side mirrors, and the nose also looks pretty close to ideal. AND it's a serial hybrid! 67mpg seems pretty darn good, too -- especially for a 7-seat MPV!
