Typical - went to Wales Saturday but as my wife was going to drive when there, we took the MINI.....thinking before hand that I'm due to see a GS (NEVER see them when I'm in mine!)......and sure as anything, I see a GS in Slough.
Black one, think it was an MCV actally. I'm not 100%, but I think it might also have been LHD, but it was on UK plates.
Also saw a very chunky looking QP on the M4 near Swindon, WU08***. MrsWoody commented on how meaty it looked.
