A car alarm is one of the most effective theft deterrents, just behind filling the driver seat with scorpions or parking your car in the living room. Beat the bad guys with today's Groupon to Mob Customs. Choose from the following options:

• For $99, you get an AutoPage car alarm with installation and two keyless-entry remotes (a $200 value).
• For $99, you get high-performance window tinting for five windows (a $200 value).
• For $175, you get a car alarm with installation and two keyless-entry remotes plus high-performance window tinting for five windows (a $400 value).

Mob Customs' automotive artists outfit vehicles in individualized style with custom alarm systems, lambo doors, rims, and window tinting. Experienced car techs secure vehicles with a premium AutoPage alarm system that alerts owners to tampering thieves and sleepwalkers. Dual remotes give other family members access and protect drivers from perpetually lost keys. Alternatively, high-performance Smoke Plus tint, ranging from 35% darkened to limo tint, shields interiors from direct sunlight. Computer-cut tints, which are quick to apply, provide a precise fit that carries a five-year warranty⎯just long enough to cover the vehicle through its midlife-crisis rim implants. Customers may opt to upgrade to a lifetime warranty for supreme window tinting for an additional fee.

Combine both options to doubly secure vehicles and keep car interiors as mysterious as David Copperfield's wand collection.
