The fact these modern cars can be taken within 10 seconds via the obd is something I've been raving about for years, you can pick these devices up from china, for £2000, a small price if your stealing 3-4 cars a week, people need to alarm there cars properly, the standard manufacturers alarm is pants, you may aswell not even have one, always go for an after market one on top of your standard one.
It happened to the BMW's now they are hitting the fords, even better if they are keyless and push button start. A lot of focus RS's have been taken this way.
£35 delivered fro the US mate sadly will do the job, 12 seconds and its done
and agreed, aftermarket alarms are the only option IMO
