Hello,
I have a 96 318is and my car does not have an alarm system and I'd like to get one on it for several reasons (one of them being that I'm tired of opening and locking my door with my key!

) . I contacted my local dealer and they said they wont be able to get an alarm system in my car and that my only option would be to get an aftermarket one. So what are my options? I did some research online and I found a huuuge difference as far as prices go. I don't really think I need anything that fancy (supersonic sensor? nah!). Any advice?
Thanks in advance!!!
