On my mega journey today I saw so many Zed's I've lost count.....here are some of them, that I can remember.........
A259 between Southwick and Worthing - two E85's one black, one silver and a silver E86 (which I see regularly on that road) (about 10am)
A24 near Worthing - a light blue (Maldives?) E85 (blatting it down the A24) and a silver E85 (about 12pm)
M23 after Crawley - silver E85 (roof up?!) about 12:30
Between M23/M25 junction (clockwise) to M25/M4 junction about 5 or 6 E85's (after 12:30)
M4 westbound between junction with M25 and Slough - two black E85's heading eastbound, three silver E85's heading westbound (around 1:15)
A312 Hayes - black E85 heading south, silver E85 heading north (5:30 ish)
M25 anticlockwise just before and after M23 junction (heading south - all the way past crawley) - silver E85 - can't remember the plate but we passed each other quite a few times, then another E85 heading south on A23 with a private plate J** something
There were more but simply can't recall all of them!
