with the interior so empty it will be easy to dry the car out. wet exhaust and oil pans don't hurt stuff, so that is no big deal. as long as water didn't get deep enough to get to the intake and fill the motor that will be fine too. even if water get into the engine you can just drain all the oil/water out, put in fresh dyno oil, run it up to operating temp, then do an oil change and call it a day.
good luck with it. lemme know if you two need anything, it's a short drive
