i feel for ya mate, I had twice in the second night of ownership, caught them an chased them away both times.....
First time at 01:30 in the morning, awoke to the alarm going spastic & two youts wedging my driver door open.... chased them off in my boxers.... pmsl.
04:30, sods came back, with a slide hammer, they slid the lock barrel out the door handle & used a small flat screwdriver to open the windows with the switch in the bottom of the lock, which also disables the alarm siren but not the imobiliser...... other half heard a noise an woke me up.. needless to say back out i went...... rozzers werent even interested!!
nevr had it touched again since....
