there use to be a spotted on here, can't find it now... unless I'm looking in the wrong place.
anyway... Today (Sunday 2nd Oct), White Capri without any markings, either a 1.6 or 2.0 as I could only see one exhaust. The reg was some thing like A 581 HPD, could have the numbers wrong and was traveling towards Reading on the A33 and turned off at the Burghfield turning.
If it was you.... well it was ME, that ran a long side in the 53 plate Passat to have a good gawp, much to the groans of the Mrs as I my son hadn't seen a Capri on the open road ( I don't think)!
