I need to add some important things on...an alarm, tint (FL), and radar detec.
Which are the best brands for alarms?...I've heard of python, rattler, hornet, and viper.I also hear the "pager" alarms don't work so well...is this true?I would like the best quality alarm, price not a huge factor over protecting my car.
And best rador detector?
Please give me some suggestions.
Thanks
