Well I haven't really used Bluetooth in my car for music, only for phone calls. But I would imagine that the Wifi sound quality difference would be audible. There was a noticeable difference between using the Nexus 5 headphone output into my car stereo aux input and streaming from the Nexus 5 to the AirMobi box into the same aux input. The Wifi sound was louder and had much more low-end.
I should warn you, though, that the AirMobi is configured in such a way that you can't access mobile data when you are connected to the wifi network. I don't really mind this, because incoming calls still come through; but you can't, for example, check your email while connected to the AirMobi. If having access to mobile data while streaming wifi audio is important to you, there is this option, which is more expensive and a bit clunkier, but will fix this problem:
