I Lived in Antioch, Ca. And this week two of my neighbors lost their cars, so I prefer buy an alarm than a car.
lmao, you didnt even say what car you have , year, model. nor did u mention what type of alarm you plan on getting. there are one way or 2 way alarms. the 2-way have a small screen and lets u know when someone breaks in. old cars are cheap since they do not require alot of security-bypassing. next time, provide proper information for good answers.
Go to an alarm shop and get a free quote. Price can vary greatly, depends on brand, installer, options, and type of vehicle you own.
