Flood damage

Here in SE PA we had the Delaware river overflow it's banks on Sunday. I
stopped at the garage of a friend to see how he made out. He had emptied his
shop Saturday and now was repainting and repairing the building. Anyway, a
local Miata owner came to him to repair his flood damaged '90 Miata that has
24,000 miles on it. My friend is waayy busy and can't take it on. He asked
me if I was interested. I dearly love Miatas but I'm up to my ears in fall
work around the house. But I'm thinking about it. Anyone have experience
with flood damage? The car was up to the windshield in water, so I assume
the interior was flooded. How well do the electronics take being submerged
for a day? How about drying out seats carpets etc?
