A vehicle window glass includes a side edge, a top edge which is oblique with respect to the side edge, and an adjustment feature for the window glass which extends in a direction substantially parallel to the top edge of the window glass. The adjustment feature can be an oblong hole in the window glass or a slideway bonded to the window glass. The window glass can be finely adjusted in the longitudinal direction of the vehicle, ensuring the top edge always follows the same oblique line. This reduces the number of steps involved in adjusting the window glass once installed in the vehicle.
