Guys,
I came across an un-marked Vectra on the M4 by Sarn yesterday. Its maroon in color, 07 reg and has twin exhaust making it the V6. It is not easy to identify as police as it has obvious arials or extra mirrors ect but it has been de-badged (i.e no vectra SRI markings)
I only spotted it as I overtook it on the down hill strech of M-way, pulled in front then put my foot down.....
To my horror I looked in the rear view to see a grill of blue lights flashing at me

. To be fair to the cop, he pulled up along side and gestered at me to slow down berfore buggering off again.
Easy one to miss on the bike - eyes open boys and girls!!
