Vehicle submerged in water - what are the typical signs?

Maybe this has been discussed before. This is about vehicles went in and under the flood.

Minsan, parang nakakatuwang isipin, halos lahat ng nagbebenta ng sasakyan sa iba't-ibang websites, kapag nakita mo yung ad nila "not flooded - money back guarantee" :happy:,. Of course, it's a marketing strategy.

Newei, ano ba ang mga typical signs na nag ala-submarine na ang sasakyan, :nonono: aside from dirty interior and carpet?

Thanks.
