man i remember the days you didnt need an alarm, i worked at TTP for a year and a half, parked my 31 there everyday and it didnt have an alarm then, never got touched, these days i dont reckon i could leave it there 3 hours before something would happen to it if it still didnt have an alarm.
Best of luck getting the car back in one piece mate.
People..... another chance for you all to realise, alarms, clublocks, kill switches....use them all!
