corner protector will surely be more than helpfull when you travel on the ghat sections regularly ,if not daily. Some potholes are very deep on the ghat sections. The front bumper of the Brio is considerably low and can touch the roads if you are at higher speeds incidently on the potholes. Corner guards are worth its mention in such situations. This view is (may be) subjective though. I travel through the ghats around 4 times a year (already twice since we bought the brio, and thankfully didnt scratch the underbody even once. Made it a point to be slow on potholes).
And god forbid, in case your vehicle gets tolled away from the noparking zone, then lower bumper scratches will be present for sure
As members suggest here, that it could fall, I would have to make sure that I get it taped with original 3M red colored tape.
Hope it works. I have ordered them now and cant cancel the booking.
