On the one hand, mudguards are a very simple accessory that does not affect anything. However, the front mudguards allow you to preserve the paintwork of the thresholds, as they protect them from sand and dirt flying out from under the wheels. And the rear mudguards protect the rear bumper and cars driving behind from them. However, again, standard mudguards are better than universal ones, screwed to the car body with self-tapping screws.
