I am trying to get an aftermarket alarm installed to my car. However, the price difference among different shops for the same unit varies too much.
For instance, one shop will sell Viper 300 (installed) for $240, whereas the other shop will sell the same unit (installed) for $300.
Does it matter which shop I go to? I have never had an aftermarket alarm, and I am afraid that they may screw up some electronic system in the car.
