Modern vehicles do not have to be undercoated...It is a rip off by the dealers to get extra money.

Modern cars are made of galvanized steel with layer of zinc......Very unlikely to rust....Lots of info on this just google it.....Any dealer accessories have to be looked at with a jaundiced eye....either not really needed or are marked up to the stratosphere. I worked as a new car (Honda) salesman once..very short tenure...I still remember the sales manager calling us all into the room and drilling into us that these add ons are a money machine for the dealership and therefore for the commission earned by the salesmen.

One other thing..If you really want a particular dealer add on by it directly from the service dept...way cheaper.
