2007 ford mustang BRAND NEW? - mustang brand bowling ball

at 2pm today, I only have my 2007 Ford Mustang, new, new, and that does not mean miles. I still live in New York, where most of the cars stolen from lot, but they tend to be devastated. So my question is ... I Should an alarm system or alarm Viper is my stock in this car good enough?. I am also afraid that someone will be professionally installed because I'm afraid to get something in my brand new car of my first new car in my life. Thank you.
