Hi guys, Found a shop in my neighborhood that installs car alarms. To install a Viper 560XV (remote start + alarm) they charge 0. This is if you bring your car and they pull their parts off the shelf. I went online an found the same alarm for ~0 + ..15 shipping. The same shop charges a 0 flat fee for installation. Now if you add up 150 + 100 = 250 as opposed to 0. As George W. put it, "The man is doing fuzzy math". I can understand margins, markups, whatever, but it's 0 extra! Makes it unjustifiably expensive for a 97 Civic. Is there something I am missing? Is it safe to buy an alarm off the web and simply bring it for installation? Thanks!
