Sorry to hear about your car Q...
This is the second horror story I have heard today.
Friend of a friend driving his clio V6 jobbie along ERITH RD this week a van pulls in front of him and slows down, A bmw pulls along side him and an audi behind they all slow him down to a stop. 2 guys drag him out of the car bash him a bit and they all drive off taking his car aswell!!!
