Used Car Buying Tips - How To Avoid Flooded Cars

Floods are now a common occurrence in our 7,107 islands, no thanks to the effect of global warming and the clogged drainages around us (who causes it? Us). You are not sure if the unit you're checking is flooded since signs of flood cannot be seen by the naked eye itself. Have a mechanic with you and a second companion (a relative or a trusted friend) to help you check and have a second opinion.

So, here are some tell-tale signs that a car was flooded:

• If there are traces of water marks or mud marks in the exterior.
• If oils look soggy and contaminated with water.
• If the engine bay looks dirty.
• If the interior has funny smells and looks dirty.
• If rust in the small hinges (most of them) are evident.
• If electronic gadgets are not working well, this is a sign (and do not attempt it since water and electronics do not mix).
• Wiring could corrode.
• And lastly, if the papers are wet. If it is, walk away.

If you encounter any of these signs, better walk away since it could be a liability in the end.
