In this lower section is all the optical fibre and electrics, all your computers etc, when they showed me mine it had an inch of water in there, you would not know. They pulled a couple of connectors off some of the electronic boxes and the pins had started to oxidise green, that was in a couple of days.

You would most likely also have water in your transmission if it was sitting there for awhile in the water. Mine was a statutory write off and only to be used as parts, it was sold at auction for $18k. Should have bought it myself, at 11 months old the 20" wheel were worth $4k, towbar $1,500, sports aero kit $3k etc
