I let a guy get away from me once when I had my Mk2 - he had a Cav GSI 2000 thing with 3 people in it and I was eating him alive! I backed off cos I knew there was a nasty looking corner coming up, he went on without lifting and crashed pretty bad!
The OSR wheel hit the kerb, the car spun twice, smacking the kerb a few more times - front and rear bumper came off roof was concertina'd but they all got out of it.
I stopped when I saw it happen in front of me - one of the guys came up to my car and asked me for a lift! I said ok, he got in, I saw he had a massive bag-o-pills in his inside pocket of his jacket so I told him to get out!!
Moral of the story - chav drug dealers can't drive. Oh, and avoid Cav GSI 2000s if you can!
