I'm not one to scaremonger but thought I would pass this on, better to make people aware than not.
I was in a off license near me in Surrey a few days ago, overheard a frightening consversation...
One of the guys behind me was telling his mate how their friend with a blue RS4 was almost carjacked. He was driving home and 4-5 men were waiting outside his house with balaclavas on & holding weapons attempting to hide in the bushes. He spotted them as he was pulling up and quickly reversed and got away.
Keep your eyes peeled chaps!
