GPS tracker

A GPS tracker connects with your smartphone to let you know the location of your vehicle at all times.

While this gadget is probably more useful for parents trying to keep tabs on their teens, it can also come in handy in the unfortunate event someone tries steals your vehicle.

The Spy Tec portable GPS tracker even allows you to set up a geo-fence and will notify you via email or text if the car goes outside the pre-determined area.

You can buy the Spy Tec portable GPS tracker on Amazon for $49.95. However, you'll also need to pay $25 a month for the tracking service.
