I picked mine up yesterday. The diesel sound is a bit noticeable when idling, but goes away pretty quickly. To be honest, the only time I hear it is when the radio is off and I am seeking out for that diesel . Meaning, if I pay no attention, it will not bother me.
The true test will be when we take a family trip and my wife is sitting in the front passenger seat with the radio off... All she wants to do is talk - at normal volume and not raise her voice over the diesel growl.
It is my first diesel, so lets see how it grows on me.
