I've now seen about a dozen around Notts - mostly white (may have seen the same car a few times), 3 black and 1 Melbourne red. All on 18s, none with Xenons that I've seen.
Several engines - most were 320d but there have been 1x 320i, 1x 318d & 1x 316d (the Red).
I think I've got the only Mineral Grey and the only Xenons in the area. Loving the adaptive lights
