You may have gotten extremly lucky...

you see, water isnt combustable.. .LOL

1. your car will probabaly be fine.. I did that in my old z28 where the intake is real low on the car.. it sucked up water... ran.. drove like shit for a few mins.. then was fine.. i figued the engine just burned up the water being so hot..

2. since when is 4 feet deep of water.. a puddle???
