Narrow down what you want to have the system do for you and research the features. Think real world use. Some people want all the bells and whistles and a week later can't remember how to roll their windows back up via remote. Stick to the basics and keep it simple.
I personally think the Clifford line is the most refined and dependable product available. However, the installation is more important that the product. The best Clifford out there won't work correctly and reliably if not installed correctly. Do your research and find a good installer you can build a relationship with and can talk to and trust.
This is great advise^
If the alarm is quickly installed and care is not taken with the installation then not only could you have potential issues with it, but it could potentially be much easier for the would be thief to defeat.
Look at brands and features, but pay very close attention to the shop you are having install it and the installer him/her self. Care taken to hide wires, sensors and generally make the alarm more difficult to spot, get to and defeat is key. Solid connections and care taken to ensure safe and reliable long term installation is a must. Might cost you a bit more install wise as it takes longer, but in my opinion well worth it.
