24-Point Checklist: What to Look for While Buying a Used Car

These Common Mistakes When Buying a Used Car

Buying a used car can be one of the smartest financial decisions you make — or one of the most costly. Every year, thousands of people end up with second-hand vehicles that need expensive repairs or have hidden histories simply because they didn’t know what to check when buying a used car.

In this complete guide, we’ll break down the 24 most important things to inspect when buying a used car, covering everything from mileage and mechanical issues to financing options and insurance. Whether you’re a first-time buyer or upgrading to your next ride, these tips for buying a used car will help you avoid scams, make informed decisions, and get the best value for your money.

Let’s walk through each step, phase by phase.

Phase 1: Before the Inspection

These are the most important things to do before you even see the car in person.

1. Determine Your Vehicle Needs

Before you start shopping, be clear on what you need. Are you commuting long distances? Do you need space for kids or cargo? Your answers will shape the kind of vehicle, size, fuel economy, and features that matter most.

Used car purchase tip: Don’t buy a sports car when you really need an SUV. Make the car fit your life — not the other way around.

2. Set Your Budget

Know how much you can afford. Include:

Down payment
Monthly payments (if financing)
Registration fees
Insurance costs
Future maintenance

What to know when buying a used car:
The sticker price isn’t the final cost — it’s just the beginning.

3. Do Your Research

Use platforms like Kelley Blue Book, Edmunds, or Autotrader to:

Compare prices across similar makes and models
Learn about common issues for specific years
See what’s available in your area

Tips for used car shopping: Researching first puts you in control when it’s time to negotiate.

4. Know the Car’s Market Value

Before you visit any seller, know the current market value of the car. This is your #1 weapon in avoiding overpayment.

Use valuation tools with accurate mileage and condition selected.

5. Ask for the Vehicle History Report

This is a non-negotiable. Services like Carfax or AutoCheck reveal:

Accident history
Flood or fire damage
Odometer rollbacks
Title status (clean, salvage, rebuilt)

Buying a second-hand car? Always get the car’s past in writing

6. Compare Insurance Costs

Not all used cars are cheap to insure. Sports cars, luxury vehicles, or models with high theft rates come with higher premiums.

Used vehicle checklist tip: Get quotes from a few insurance companies before committing.

7. Explore Financing Options

Never rely solely on dealer financing. Shop for:

Credit union auto loans
Bank auto loans
Online lenders

Ask about used car financing:
Pre-approval gives you leverage and clarity.

Phase 2: During the Inspection and Test Drive

This is where you roll up your sleeves. These are the things to look for when buying a used car on-site. Bring a checklist, your phone, and a flashlight if needed.

8. Inspect the Exterior

Walk around the car in daylight. Check for:

Dents, rust spots, scratches
Paint inconsistencies (may signal repairs)
Properly aligned panels and doors

One of the top things to look for when buying a used vehicle is hidden damage poorly covered with cosmetic fixes.

9. Check the Tires

Look at all four tires for:

Uneven wear (could indicate alignment issues)
Tread depth
Matching brands and tire age

Uneven tread can suggest frame damage or suspension problems — major things to inspect when buying a used car.

10. Inspect the Frame and Undercarriage

Check underneath for:

Rust, especially on the chassis
Bent or damaged structural parts
Fresh undercoating (may hide rust)

The frame is the car’s skeleton. A compromised frame is one of the most dangerous red flags when buying a used car.

11. Pop the Hood: Check Under the Hood

Inspect:

Oil level and color (milky = coolant leak)
Hoses and belts (cracks = wear)
Battery terminals (no corrosion)
Leaks or strange smells

This is one of the most critical things to check when buying a used car. Don’t skip it — or bring a mechanic if you’re unsure.

12. Evaluate the Interior

Check:

Seat condition (tears, smells, stains)
Dashboard lights (all should light up, then go off)
Window controls, radio, AC/heat
Trunk and spare tire compartment

Things to look for when buying a used car go beyond the engine — comfort and functionality matter too.

13. Test the Upholstery

Don’t just look — sit. Feel for:

Sagging cushions
Broken seat adjustments
Musty or smoky smells

Smell is harder to fix than most mechanical problems. It’s a subtle but vital item on your used vehicle checklist.

14. Take a Test Drive

Always test drive the vehicle under different conditions:

Highway, city, tight turns, braking
Check acceleration, steering, suspension
Listen for clunks, rattles, hesitation

A solid test drive is the best way to discover mechanical problems not visible during an inspection.

15. Watch for Dashboard Warning Lights

If any lights stay on (check engine, ABS, airbag), that’s a sign of trouble. Make sure the seller didn’t reset the system to hide issues.

It’s one of the most common traps in buying a second-hand car — don’t ignore the dash!

16. Check the Brakes

During the test drive:

Brake hard and gently
Listen for squeaks or grinding
Feel for vibration or soft pedals

Faulty brakes are a dealbreaker. Tips for buying a used car always include checking brake safety.

17. Ask About Maintenance and Service Records

Ask to see:

Oil change receipts
Brake/tires/battery replacements
Timing belt (if applicable)

A well-documented service history is a great sign when buying a used car — it shows responsible ownership.

18. Get a Mechanic’s Inspection

Even if the car feels fine, this is non-negotiable. A mechanic can find:

Transmission wear
Hidden leaks
Frame damage
Engine health

One of the most essential used car purchase tips: don’t buy without a professional inspection.

Phase 3: After the Inspection — Ready to Buy?

This phase covers final checks before you put money down. You’ve done the research, test driven the car, and inspected everything — now let’s wrap it up wisely.

19. Ask the Right Questions

Always ask:

Why are you selling the car?
Are you the first owner?
Any known issues or recent repairs?
Can I see the title and registration?

Asking smart questions is part of how to purchase a used car without regrets.

20. Review the Title and VIN

Match the VIN on the:

Dashboard
Title
Door frame

Look out for:

Salvage or rebuilt titles
VIN tampering

This step helps you avoid scams — a crucial point in any buying a used vehicle checklist.

21. Review Used Car Financing Terms

If financing:

Compare dealer bank rates
Avoid loans longer than 60 months
Know your credit score

Ask about used car financing options before you sign. Don’t fall into high-interest traps.

22. Review Insurance Requirements

Make sure:

You have insuranceready before purchase
The car doesn’t spike your premium

You consider gap insurance if needed

Planning ahead is a big part of what to know when buying a used car — especially regarding protection.

23. Compare with Other Vehicles

Still unsure? Pause. Recheck online listings to compare:

Mileage
Price
Condition
Features

One of the smartest tips for used car shopping is not rushing. Patience pays off.

24. Negotiate Wisely

Based on:

Market value
Any repairs needed
Competitor pricing

Start lower and work your way up. Don’t be afraid to walk away.

In most provinces/states, used car sales are final unless the dealer offers a return policy. Always ask before purchasing.

How do I know if a used car is a good deal?

Compare it to online value estimators and inspect it thoroughly. A good deal balances price with condition and longevity.
