I was initially worried about the noise levels, especially for a man of my years...
So far, I still quite like the 80's rally car flutters you get... It makes a nice change to the big puutshhh from other things..
Noise when on the motorway is really noticeable, jousts blends in to the road noise and a little volume from the wireless helps hide it..
If you notice the speed at which they go when advertised in the For Sale section, then you can always move it on if you can't live with it..
