What is the most important thing to check before buying a Kia Rio?

I am considering buying a Kia Rio, but I want to make sure I am making the right choice. What should I look for when inspecting a Kia Rio before purchasing?

When inspecting a Kia Rio, make sure to check the engine oil level and quality. This will give you insight into the overall health of the engine.

Another important thing to check is the condition of the tires. Make sure they have adequate tread and are not worn down, as this could lead to safety issues and additional expenses in the future.

Don't forget to test drive the car and pay attention to any strange noises or vibrations. This could be a sign of a deeper mechanical issue.
