I must admit that when I first bought my Scooby and noticed people waving I was a bit confused, it was only after a few days that I realised that it was only Subaru drivers. I thought to myself what a nice bunch of people.
I think with OMD volume level 20 on the standard Subaru stereo would be just right, until Maid of Orleans, Joan of Arc came on, then wack it up.
