hey guys i am looking at a new or new to me truck. its an 09 1500 sierra with a 5.3l. my previous vehicle was a 2007 envoy that was stolen from my driveway for stereo atv and trailer. around this part of the woods gms are known for being stolen by the natives. so my main question is what do you guys have on your trucks for theft prevention? alarms, kill switches imobilizers? my only other option is to not buy a gm which is really hard to do.
