Do your own inspection. It’s basic, but give your car a once-over periodically so you catch anything that looks out of the ordinary. Make sure all your lights are working. Check the air pressure in your tires every month or so buy a tire air pressure gauge and keep it in the glove compartment. Doing so is good for your tires, gets you better mileage, and saves you money in gas if you discover that the pressure is off. Listen for any strange sounds, inside and out. Make sure your tires have enough tread. You can use a penny to do it, or look out for the wear indicators on the tire treads. If anything’s out of the ordinary, don’t ignore it.
