Used Car Buying Guide: What to Check Before You Buy

1. Check the Vehicle’s History

Before getting serious about a used car, check its history. A vehicle history report can reveal important information such as previous accidents, title problems, reported mileage, number of owners, and available service records.

Look for red flags such as a salvage or rebuilt title, inconsistent mileage, repeated accidents, or long gaps in maintenance history. A clean history report does not guarantee a perfect vehicle, but it can help you avoid costly surprises.

Smart Choice Tip: Always compare the VIN on the vehicle with the VIN shown on the title, registration, and vehicle history report.

2. Inspect the Exterior and Body

Walk around the vehicle carefully and inspect the body from different angles. Look for dents, scratches, rust, mismatched paint, uneven body panels, or gaps that could indicate previous accident repairs.

Check the headlights, taillights, mirrors, windows, and windshield for cracks or damage. Also look underneath the vehicle for signs of leaks or visible damage.

Smart Choice Tip: Check the vehicle in daylight whenever possible. Sunlight can make paint differences, dents, and previous body repairs easier to spot.

3. Check the Tires and Wheels

Inspect all four tires for adequate tread depth, cracks, bulges, or uneven wear. Uneven tire wear may indicate alignment, suspension, or steering problems.

Make sure all four tires are the proper size and check the wheels for bends, cracks, or significant damage. Don’t forget to check the spare tire if the vehicle has one.

Smart Choice Tip: Tires can be expensive to replace. Worn or mismatched tires can give you additional negotiating power when discussing the purchase price.

4. Inspect Under the Hood

Open the hood and look for obvious signs of leaks, corrosion, damaged hoses, or loose connections. Check the engine oil and other accessible fluid levels and look for anything that appears unusually dirty or neglected.

Listen to the engine while it is running. Pay attention to unusual knocking, ticking, squealing, excessive vibration, smoke, or warning lights that could indicate a mechanical problem.

Smart Choice Tip: If you’re not comfortable evaluating the engine yourself, have an independent qualified mechanic perform a pre-purchase inspection before you buy.

5. Check the Interior and Electronics

Sit inside the vehicle and inspect the seats, carpets, headliner, dashboard, and interior trim for excessive wear, stains, damage, or unusual odors.

Test the air conditioning and heater, power windows, door locks, mirrors, lights, horn, infotainment system, backup camera, USB ports, and other electronic features. Make sure dashboard warning lights illuminate during startup and then turn off normally.

Smart Choice Tip: Test every button and feature before buying. Small electrical problems can become expensive repairs later.

6. Take a Test Drive

Drive the vehicle on different types of roads and at different speeds when possible. Pay attention to how smoothly the engine accelerates and how the transmission shifts.

Test the brakes, steering, and suspension. Listen for unusual noises, vibrations, rattles, or pulling to one side. Make sure the vehicle feels stable and comfortable during normal driving.

Smart Choice Tip: Turn the radio off during part of your test drive so you can hear noises from the engine, suspension, brakes, or tires that might otherwise go unnoticed.

7. Review the Maintenance Records

Ask the seller for maintenance and service records. Regular oil changes, scheduled maintenance, and documented repairs can tell you how well the vehicle has been cared for.

Look for major repairs and check whether important maintenance services were completed at the recommended mileage. Missing records do not necessarily mean the vehicle was neglected, but they are a reason to inspect the vehicle more carefully.

Smart Choice Tip: Compare the maintenance records with the vehicle’s mileage and history report. Consistent records can give you greater confidence in the vehicle’s condition.

8. Check the Mileage and Ownership Costs

Consider the vehicle’s mileage along with its age, condition, and maintenance history. A higher-mileage vehicle that has been properly maintained may sometimes be a better choice than a lower-mileage vehicle with poor service history.

Before buying, estimate the ongoing costs of ownership. Consider fuel economy, insurance, registration, routine maintenance, tires, and the potential cost of future repairs.

Smart Choice Tip: Don’t judge a used car by mileage alone. Look at the complete picture — condition, maintenance history, reliability, and total ownership cost.

9. Get a Pre-Purchase Inspection

Before making the final decision, consider having the vehicle inspected by an independent qualified mechanic. A professional inspection may uncover mechanical, electrical, suspension, brake, or other problems that are difficult to identify during a normal test drive.

If the seller or dealership refuses to allow a reasonable independent inspection, consider that a warning sign. The cost of an inspection can be small compared with the cost of unexpected repairs after purchasing the vehicle.

Smart Choice Tip: Ask the mechanic for a written inspection report. You can use the findings to decide whether to buy the vehicle, negotiate the price, or walk away.

10. Review the Price and Final Paperwork

Before agreeing to buy, compare the vehicle’s asking price with similar vehicles of the same year, make, model, mileage, condition, and features. Remember that the advertised price may not represent the total amount you will pay.

Review all paperwork carefully before signing. Confirm the VIN, agreed purchase price, taxes, registration fees, financing terms, warranties, and any additional products or dealer fees. If something appears that you did not agree to, ask for an explanation before signing.

For a private-party purchase, make sure the seller has the proper title and that the information matches the vehicle and seller. Check your state’s requirements for transferring ownership and registration.

Smart Choice Tip: Focus on the total purchase price, not just the monthly payment. A lower monthly payment can sometimes mean a longer loan term and a higher overall cost.
