One was a black blob eye, with two (i think, windows were tinted) asian lads turning on to the Ruislip road east, from the Gurnell swimming pool area, heading towards greenford.

Same area as above except it was navy blue had silver and gold rims, single driver, couldnt tell ethnicity.

Another black scooby newish, following me on the A40 (A carriageway) after hanger lane gyratory towards Hanwell / Ealing exit slip.
