Never see an E9 on the road up here. Not too long ago I was actually "out there" on the way to a wrecker to find a part for my E39 Touring, when I became aware of some "Jason Bourne"- type driving manoeuvres behind me, amongst the traffic. At every light, there was some jockeying amongst the cars in 2 lanes. As the light changed to green, I had to keep my eye on all of my mirrors as a 3 series BMW was cutting in and out of the spaces between the cars and eventually along the shoulder. Finally came to understand, driver just wanted to show his companion, a genuine BMW 3.0CS Coupe. He had actually never seen one "in the flesh" and wanted to show her one of his "other" fantasies .
Cannot be too careful!
