If you are not confident in evaluating possible damage, stay away. But, just because it says flood damage in the history does not mean the car got wet. It just means it was towed out of a flood zone. Some of the flood cars are toast and I wouldn't even want many parts off of them. Others are not bad deals. I have no idea what the ratio of good to bad would be.

I have looked at a lot of them but I have never bought a car with a salvage title of any kind.
