No, sir, I will NOT be buying your truck OR ANYTHING ELSE

Actually we don't know that is true. It might have gone in a "lot deeper" than the photo shows, and might have been there "all weekend" or at least overnight. Flooded modern overly "electrified" vehicles can be a lot of trouble
Or the water level may have been higher and now its down etc. I once redid a flood Mustang when I worked at the ford dealer, it was new carpet, and all the oils changed, then the detail shop took it and did their thing to it.
