A Couple of weeks ago, I got a Compustar Remote Car Starter installed from Derdall Designs. Though all the dealers in Calgary be doing a great job by I noticed that even very small things mattered with them. I got my Car neat and clean - like you can't tell it something has changed in there. All wires and system hidden and the system working like a Charm. The guy there explained very patiently the difference between systems, how to work on the remote (though it was coooold outside and he was only with his shirt on), I took my time to understand everything and he never got in hurry. Not only this - while waiting, they suggested if anyone needed a ride to Chinook centre while working on car, they would drive to. I believe, these guys should be given chance to work on your car. Highly recommended.
I'm not their sponsor or anything, just a happy customer with good job done.
