Ok I want to buy myself a radar detector and I've heard a lot of positive things about Escort XRS-9xxx series and they INTELLIMUTE technology wich reduces false alerts by monitoring the RPM of your car. What I wonder is whether I should purchase the OLD Escort 8500 Model (the 2001) or the new Cobra XRS-9300. I wonder which is has a greater sensitivity, greater range and greater accuracy. I know that the original Escort 8500 does false a lot since my friend has it so the people who say that Escort 8500 is false alarm free are lying. So now the question is: Is Escort 8500 better then Cobra XRS-9300 when it comes to detection, range and falsing or is Cobra XRS-9300 equal to Escort 8500. And I am talkinga bout the vanilla Escort 8500 not the new X50 model. Since what I will be buying is the Escort 8500 Vanilla and not X50. My friend wants to sell me the Escort 8500 for $150 so I have to choose between Cobra XRS-9300 for $70.0 or the Escort 8500 for $150. Is the extra $80 really worth it when it comes to Escort 8500? Also does the cobra INtellimute actually works? Does it effect the range?
