no matter what theives know what an alarm looks like
if the wires are coloured and they have an instruction booklet then they know what to do with each wire
but if they are all black, they have to trace them
prob ignition fuel and some thing else i cant remember.
is your alarm wiring black? if so there not going to be able to start it in minutes, may take them a while.
and if he was that skilled they would have opened you car at least already
also make sure nothing visible valuable is showing, or find a new parking spot. one where there's always people walking by.
i dont think they will tow it. if they wanted in like that, y would they break the lock and make u more cautious?
