that sucks. like other posts did he have clublock, kill switch, pager alarm etc?? if not sorry no sympathy.
my GTR had a kill switch that i had to press when turning from ACC to start the car and no one could find it (several high end alarm installers mechanics and people who now how to find where kill switches are). cost bugger all but couldnt not be started.
these days you cannot be too safe and have atleast three forms of security for your car.
AND yes i have had a car stolen and burnt out from my backyard that only had alarm that with time could be turned off (a day after new engine was put in from workshop), so i am speaking from experiance as long term MATURE skyline owner as many older people from this forum would know.
**if any of the moderators feel this should be deleted that is ok, just putting my point of view across**
