Electrical problems today, and in the future, from corroded connections, are the biggest problems that come with ALL water damaged vehicles. Most competent mechanics, and DIY's, can deal with mechanical problems and wet floors/walls, but electrical problems, especially badly corroded connection problems, can cause intermittent electrical gremlins to show up in various electrical circuits as well as engine and transmission control boxes. Repairing these issues can be very expensive and very frustrating for the usual mechanic and the hourly labor rate can quickly make that bargain purchase in to a black hole that may never be free of problems.
