When you buy a car from Carmax you are protected with your warranty and we have the technicians you need if things go wrong.
When your car is acting up or breaks down, the last thing you need is a communication breakdown with your technician. Learn how to describe certain sounds with Lesson in Sounds: around the vehicle or Lesson in Sounds: under the hood. Get an idea of what the leak spots on your driveway might mean in Lesson in Liquids. Then next time you make a trip to the repair shop, you and your technician will be talking the same language.
