What kind of alarm system or anti theft deterrent systems would be ideal for a late 60's or early 70's type car that has to sit outside and cannot be garaged due to lack of available garage space....

I want another fair weather, daily type Mopar that I can rest a little easier with when it sits outside at my house or at work and would like to get some ideas from you guys as to how to "minimize" the risk of theft.

Thanks in advance.....!!!
