Seen today on the way home (in Bierton, just North of Aylesbury) - an all black new "S" with what looked like a bodykit (Aerokit?)
Only seen for a few seconds, but looked like a pretty deep chin spoiler (bit like a Hamann spoiler), coded black arches (or possibly shiny black tape, but looked good), rear bumper treatment similar to current aero kit (but difficult to see details in mirror).
4 up with guys in green fluoresecent vests
Still with black tape around headlights, making them look tiny - first thing that caught my attention, otherwise probably would have thought cool-looking, all-black
JCW.
On the way back fom MIRA?
