What would we love to have in our cars now that temperatures are plummeting? A remote starter. What's really expensive and difficult to install? A remote starter. This Remote Control Interior Car Heater ($150), on the other hand, is a breeze to set up, and costs a fraction of the alternative. We can even set its timer to start exactly when we want it to, so our morning-blurred brains won't even have to remember to press the button.
