How Water Proof

Doors. Rear doors leak the most. But other doors will leak also. No car is water proof. Spend as little time as possible in the drink to avoid water inside.

I can't answer your question specifically, but I was told to close all the windows and put the fan on maximum speed with the setting to bring fresh air into the vehicle. The idea is that the interior is slightly pressurized. Either my 80 is totally water tight (water to the door handles) or the fan thing works.

It's also good to keep dust out (unless you're following someone.)

rlbye - its difficult to answer your question as i've owned some 14 4wds and i think that they've all leaked incl. my current gu3 - its strange but i can remember time of door handle depth water crossing with no water and the same car leaking (normally back passenger doors) in less water - one thing is for sure though 4wd's are not boats and i've seen some of the lighter versions attempt floating!!!!

The headlights are not sealed and will fill up if submerged. You gotta go pretty deep to do that but it has been heard of.
