I don’t know 2 feet of water and all.
Once the salt got to the car, it was scrap. I saw a 300Z die that way on LBI in New Jersey. I lived in an area where the the wind and high tide would put 18”+ of salt water in the streets. I saw lots of folks leaving a wake as they drove through. I often wondered how long it was before the mysterious electrical problems showed up. I’m sure that happened before the rust made major progress on the under carriage.
