5 Key Things to Check When Buying a Used Car

Buying a used car requires diligence and attention to detail. Don't let a hidden problem ruin your investment. Here are the five critical inspections our experts recommend before purchasing any used vehicle.

1. Examine the Exterior Body and Paint

Start with a thorough visual inspection. Look for dents, scratches, rust spots, or mismatched paint that might indicate previous accidents or poor maintenance. Check all panels, under the doors, and around the wheel wells where rust commonly develops. Rust repairs can be expensive and may indicate the vehicle's condition history.

2. Check the Tires and Brakes

Tire condition directly impacts safety and your immediate expenses. Look for uneven wear patterns, which can indicate alignment issues. Use the penny test: insert a penny into the tread with Lincoln's head upside down. If you can see the top of Lincoln's head, the tires are too worn. Brake pads should also be inspected—replacement can cost $300-600 per axle.

3. Review the Service and Maintenance History

A well-maintained vehicle is a good investment. Request complete service records to verify oil changes, repairs, and maintenance. Regular maintenance indicates an owner who cared for the vehicle properly. Missing service history can indicate neglect or hidden issues that might emerge soon after purchase.

4. Inspect the Engine and Fluids

Open the hood and check fluid levels and condition. Oil should be brown or black—not light colored, which suggests recent top-offs. Coolant should be clean and at proper levels. Check for leaks under the car and around gaskets. Listen to the engine for unusual noises, knocking, or grinding sounds that could indicate serious mechanical problems.

5. Test Drive Thoroughly

Never skip the test drive. Accelerate smoothly to check transmission response. Test the brakes at various speeds. Listen for unusual vibrations or sounds. Try the power windows, locks, air conditioning, and other electrical components. Pay attention to steering feel, suspension, and overall handling.
