Helped pull out a friends car here which got flooded out when he drove thru high water; it was done under pressure because it was pouring, wife screaming at me not to do it etc I was up to water about a quarter of the way up and none got in (thank god). I have a snork which i have not installed yet but are there ways to seal up the doors for better water protection?? ( I have a 99 lx 470)
