The big one (Pasteur road I think, or something like that) I did try waving but not sure you saw and put my hazards on after you went past as I left it a little late (I was in the middle of preparing to turn off on the mini roundabout) Didn't see what reg but I was in the black 370Z (probably heard me before you saw me to be honest)........
EDIT: Was about 1530hrs I think.
