As one of its daily deals, Best Buy offers the Viper Remote Car Starter System, model no. 4103V, bundled with the XPRESSKIT Databus DBALL All-In-One Interface Module and Geek Squad Viper Remote Start and Security Add-on Installation for $199.99 with free shipping. That's $280 off list and the lowest total price we've seen for this Viper system complete with installation. (We saw it for the same price last winter, but without the interface module.) The car starter system includes two remotes with four buttons (including lock, unlock, trunk release and remote start), and Xtreme capacity relays. The DBALL functions as a door lock and override module. Deal ends today.
