Hey fellow V6P'ers, Im shopping for an alarm & remote start. I need your guys suggetions or any experience with the product would be nice (pros & cons). I have come down to these two; Viper 5900 and Compustar Pro P2W9000FMR. I read some threads about these two brands but I want to hear more about it especially from this site. Price w/ installations is around $500 more or less. TIA.
