not impossible, so aside from your alarms with immobilizers, it helps to use the old fashioned steering wheel lock, and wheel clamps (if you have one)

maganda rin siguro kung may kill engine switch na you have to turn on for the ignition to work..

sa motor nga bukod sa kadena sa disk brake yung iba tinatanggal pa cdi nila eh. para kahit susian hindi tatakbo makina..
