the alpine... They told me it would cost 300 dollars with installation. Id add another 80 dollars for the door actuator (solenoid), 80 dollars for the window actuator (solenoid) and another 100 for an automatic starter. But thats the cost for the clifford. U can get all those features from an alrm that runs at 100 dollars like say the prestige, hornet, commando, etc..... They all do the same thing and they all come with all those add-ons. if ur looking to save some cash then go with the cheaper brand. No need to spend more money for a product that does the same thing that offers the same warantee. Up to u. Good luck on ur purchase.
