Water damage fingerprints in used car?

I am searching for a used car in Hampton Roads, Va. In the last year we have had two significant tidal flooding events. I don’t want to get someone else’s problem. How do I check, will such an issue show up on car fax?

If you smell mildew or find the vehicle has electric Gremlins,keep looking-Kevin

Take it to a mechanic who knows how to check for water damage and have them give it a thorough look through

Take a stick with a rag taped to the end and stick it up the the floor vent for the heater to see if there is dirt,mud on it.
