Went with my friends to the junk yard on sunday for them to get some civic parts. Walked by a bmw exactly like mine. man the whole front was gone interior ransacked but what did I see peering out but an alarm siren-took it off and wow only paid $15. I originally did the radio shack siren DIY but was glad to plug siren right in and worked like a charm. Also snagged the microphone from the overhead and the gm5 module, the girl asked what they came out of oops Buick just rolled out. $3 each piece. LOL. No tilt sensor or motion sensor though :-(. Really was hoping passenger window regulator but that was the only door missing off the car. Just thought I would share. I am now a junk yard ***!!
