It’s no exaggeration to say that the smartphone has changed everything, including how we interact with our cars. Most carmakers offer some sort of connected smartphone app, but some are better than others. Look for one that lets you remotely lock and unlock the doors, check the status of things like fuel and tire pressure, and even remotely start the car to warm things up on a cold winter’s morning.

Make sure to ask if there is a monthly or yearly subscription fee for the service, as it can vary from carmaker to carmaker.
