CARFAX told potential buyers of used cars to check the seven signs of a flooded car:
2.Loose, stained, or mismatched upholstery and carpeting
3.Damp carpets
4.Rust around doors, under the dashboard, on the pedals, or inside the hood and trunk latches
5.Dried mud or silt in the glove compartment or under the seats
6.Brittle wires under the dashboard
7.Fog or moisture beads in the interior lights, exterior lights, or instrument panel

...and the number 1 sign. Fish in the glovebox.

I was going to say fish shooting out of the air vents when you turn on the A/C.

Happens after every flood...
