and I just left there last Friday. What I see is someone who had an opportunity to declare on a car they didn't drive.
I've lived on the water most of my life and have been flooded many. The tell tale signs of salt intrusion I do not see in the photos, which are just photos but the storm was back in October so some drying would have taken place and salt residue would be present. Even if you rinse the car down, every time moisture is present any moisture in the air will activate any salt residue and it reappears, as salt is a desiccant.
There is some pitting on the spedo bezel but any car will get that if not in a climate controlled environment. The engine would certainly be effected as the alternator and AC compressor are aluminum.
My neighbor had a Cadillac and water came up to the wheel rims and they totaled it because it was in a flooded area. During Florence I had 9 foot of water in my garage but had moved my Speedy and 911 to a friends garage in the same area, his house was dry yet six houses down from him had water in their houses.
If I had moved my cars back to my flooded garage it would have been a photo op.
