If you drive a vehicle with more than a few miles on it, there’s a good chance you’ve noticed an occasional drip underneath it that leaves spots wherever you park. Identifying what is leaking from your car will help you determine whether or not it’s a cause for concern, and what to do about it.

Your Vehicle Identification Number, or VIN, is essentially your car’s fingerprint. In its entirety, it is specific only to your car. Each car has its own unique VIN number, and can be decoded to provide manufacturing and identification information on any vehicle on the road. Date of manufacture, manufacturer, vehicle type, where it was made, and options such as engine and transmission type, whether a car is a two or four door, and a multitude of other specifications can be gleaned from a VIN number. Essentially, a VIN number will tell you exactly what a car is and where it came from, without even having to see the car.

Unfortunately, sometimes sellers aren’t particularly straight-forward with their used cars. Many will try to hide the fact that it’s been damaged by flood waters at all, or try to convince potential buyers that the car is in fact fine. “It has gone months with no issues” or “technically it is flood damaged but” are two red flags, and while it isn’t impossible for a flood car to be fine, it’s altogether a good idea to stay away.
