If the speed of the car relative to the wall is fast enough then depending on the shape and size of both objects both would break or only one would break unless the car bounced backward in the opposite direction from the reference frame in which the wall is stationary before the collision but then the momentum would have to transfer moving the ground the wall is attached to together with the wall so that to an observer standing on the ground it apoears not to move
