Nobody asked the most important question: Was it fresh water or salt water.
Fresh water, yeah pull plugs and crank. You already did everything else. Salt water, don't bother, the salt will eat away at everything and the car is pretty much effed.
Talked to a lot of guys the spring after Superstorm Sandy at Raceway park. There was 25,000 cars at RP all from NYC. Exotics, antiques, DD's, you name it. All salt water damaged, all taken off and sent to the big junkyard in the sky. Then a few guys had flood cars from fresh water. Interiors had to be ripped out, dash boards, etc, but after drying out, these cars are back on the road. One car, a converitble, was full of sand, all the way up to the doors. That car had to weigh a few tons!
Not saying that's what you have here, but just to give you an idea
