Explanation:

- Depose: This means to remove someone from office or position, typically a high-ranking one. It's not relevant here as it isn't about getting rid of a physical object like a car.

- Deal: This usually means to manage or distribute something but doesn't fit well in the context of getting rid of a car.

- Devoid: This means lacking or being without something. This word doesn't suit the context because it's unrelated to disposing of objects.

- Dispose: Refers to getting rid of something. It's the most appropriate choice for the sentence about not being able to get rid of an old car.
