Anti theft

Could anyone provide me,as a guide, a price to install full anti theft device in a new 325CI?
Thanks

Your car came pretty well equipped as far as anti-theft goes, no key, no why to make it start and if someone really wants something out of the car there's much of a way to stop them except an armed mercenary, which does get pricy..........

If you're looking to get a better anti-theft system, or just one in general, a viper system is wonderful. I had a Viper alarm put on my 325i a year and a half ago and have loved it. The one I had installed only cost $200 but has been wonderful. My alarm has the typical keyless entry, and shock sensor with nice loud speaker, but it also has a starter-kill which will dissable the engine if someone tries to start it while the alarm is armed. Since I've had it installed, the viper systems have continued to advance, and you'll have to see what all features you want, but you should be able to check it out at a local Circuit City or local car stereo shop!
