who cares if its a 88 Taurus? does it really matter what this is going into?
Older 'clunker' cars with systems are targets for stereo theft. I grew up seeing it every week. Some high school kid would dump $1000 on a stereo for his civic and 2 weeks later it would be stolen out from in front of his house with him finding his car torn apart in the morning. You can't tell me with a straight face that a newer car is just as likely to get broken into for its stereo as an older car. Yes, its done... but not nearly as frequently. Easy targets are just that... easy targets. I'm sure an '88 Taurus has much less security than even say a '00 Taurus (for comparisons sake). Regardless of whatever aftermarket alarm you tap into it.
