It
go without saying, but a key element for maximum enjoyment of a car wash (and they're pretty fun, let's be honest) is making sure your car is water tight.And if you needed a reminder as to why, then just watch this video doing the rounds today showing what happens when you forget to close the sunroof.
These people had the interior, non-waterproof screen closed but forgot to shut the outside bit leading to this sweary but funny video.
Never forget.
