Thinking about buying a used car?
Before you hand over the money, make sure you know exactly what you’re getting into. I’ve bought, sold, and repaired dozens of cars over the years — and I’ve seen almost every trick in the book.

That’s why I created this complete used car inspection checklist, based on real experience — not theory. Bookmark it, save it, and read carefully before you go car shopping!

_{1. Before Meeting the Seller — Ask These Questions First}

(Don’t send all at once, or they’ll cherry-pick what to answer.)

1. Has the car ever had major repairs (engine, transmission, accident damage)?
2. Are there any current problems?
3. Can the car pass the emissions test in its current condition?
4. When was the last oil change?
5. Is there any rust on the undercarriage or body?
6. How many keys come with the car?
7. Do all keys work properly?

If the answers sound good, set up a time to see the car — during daylight. Ask the seller not to pre-warm the engine, so you can see how it starts from cold. And make sure all keys are available for testing.

_{2. On-Site: Check the Exterior and Tires}

Pro tip: Don’t let the seller talk too much while you’re inspecting. Stay focused.

• Look for dents, scratches, or cracks on the body (say them out loud so the seller hears).
• Check if the tire tread is even and deep enough.
• Confirm the tire age — ideally less than 5 years old.
• Make sure the spare tire is present and inflated.

_{3. Mechanical Inspection (Cold → Hot)}

1. Test every key for remote unlocking.
2. Check engine oil level before starting.
3. Turn ignition to “ON” and confirm the Check Engine Light comes on.
4. Start the car and observe the temperature gauge — if the engine’s already warm, ask when it was last driven.
5. Check the exhaust pipe for smoke or strange smell.
6. Listen under the hood for unusual noises during the first 15 seconds.
7. Inspect the battery terminals for corrosion.
8. Engine bay should be dry and clean — water stains or oil leaks are red flags.
9. Verify transmission fluid, brake fluid, and coolant levels.
10. Crawl under the car and check for leaks or rust.

_{4. Electrical and Interior Systems}

• Headlights, high beams, turn signals, brake lights, reverse lights, plate lights.
• Test handbrake, windows, and door locks from every seat.
• Check trunk struts (should hold up by themselves).
• From driver’s seat, operate all windows and sunroof.
• Test horn, wipers, washer spray, radio, speakers, A/C, and heater.

_{5. Test Drive Like a Pro}

Try to drive alone — sellers talking can distract you from noticing issues.

• Reverse gear should engage smoothly.
• Gauges and dashboard indicators must work.
• If 4WD, test activation and deactivation.
• Turn steering wheel lock-to-lock; it should be smooth and quiet.
• Brake test: firm, responsive, no squeal or grinding.
• Try cruise control.
• Accelerate hard — automatic shifts should be smooth.
• Drive at least 8 miles (over 60 mph) — watch for vibrations, noise, or pulling.

_{6. Before Making an Offer}

• Spend a few dollars on a Carfax report — it’s worth it.
  • More than 3 owners? Think twice.
  • Seller recently bought it? Could be a flipper.
  • Big repairs not disclosed? Ask directly.
  • Gaps in maintenance history? Find out why.
• List all issues you found and call a mechanic for rough repair estimates. It gives you strong negotiation power.

_{7. Negotiation Tips}

Every flaw you find is a reason to negotiate — even if you don’t plan to fix it.
After listing the problems, name your price immediately while the seller is still thinking.

_{From Wrenches to Code: Why I Built CarMind}

I created this checklist the hard way — through years of mistakes, repairs, and learning. I used to rent a small house with a garage where I fixed my own cars, helped friends inspect theirs, and rebuilt more engines than I can count.

But I kept asking myself:

“Why can’t everyone have a mechanic’s brain in their pocket?”

That’s why I built CarMind — your AI car inspection assistant.

Unlike regular OBD2 scanners that only read trouble codes, CarMind goes deeper.
It connects to your car’s sensors in real time and analyzes the data — just like a mechanic listens to the engine, looks at exhaust color, or smells for fuel leaks.

Even if no warning lights are on, CarMind can detect hidden issues early, explaining in simple language what’s wrong, why it matters, and roughly how much it might cost to fix.

👉 Available now on iOS (search “CarMind” on the App Store) — works with almost any car made after 2008.

_{The Mission Behind CarMind}

I’ve always believed people who understand cars should share that knowledge with those who don’t.
CarMind is my way of doing that — a gift to my younger self and to every driver who’s ever been nervous about buying a used car.

If you’re shopping for a used car or just want peace of mind about your current one,
try CarMind — let AI inspect your car like a real mechanic.
