How to Check a Used Car Before Buying

15 things to verify before you hand over your money. Start online, finish in person.

1.
Run a VIN check

Before you even visit the car, decode the VIN online. Verify that the make, model, year, and engine match the listing. Check for open safety recalls and stolen vehicle records.

2.
Compare VINs on the vehicle

When you see the car, check the VIN on the dashboard, door jamb, and registration. All must match. Mismatched or missing VIN plates are a major red flag.

3.
Inspect the body for accident damage

Look for uneven panel gaps, mismatched paint, overspray on rubber seals, and fresh undercoating. Run your hand along panels — ripples indicate body filler. Check under the trunk carpet for wrinkles or fresh welding.

4.
Check for rust

Inspect wheel arches, rocker panels, door bottoms, and the undercarriage. Surface rust is cosmetic, but structural rust (frame, subframe, floor pan) can make a car unsafe and uneconomical to repair.

5.
Verify the odometer

Compare the displayed mileage with the service history stamps, MOT/TÜV records, and the overall wear. A car with 50,000 km should not have a heavily worn steering wheel. In Europe, odometer fraud is estimated to affect 30-50% of cross-border used car sales.

6.
Check the engine bay

Look for oil leaks, coolant stains, corroded battery terminals, and non-original parts. A clean engine bay on a high-mileage car may indicate steam cleaning to hide problems. Check the oil filler cap for milky residue (head gasket issue).

7.
Start the engine cold

Always arrive with the engine cold. Blue smoke on startup indicates oil burning. White smoke may indicate a head gasket leak. Listen for knocking, ticking, or rattling noises during the first 30 seconds.

8.
Test the electrics

Check all windows, mirrors, locks, lights, indicators, air conditioning, heating, infotainment system, and seat adjustments. Electrical repairs are expensive and often indicate broader wiring issues.

9.
Inspect the tires

Check tread depth (minimum 3mm for safety), uneven wear patterns (alignment or suspension issues), and tire age (DOT code — tires older than 6 years should be replaced regardless of tread).

10.
Test drive on varied roads

Drive at city speeds, highway speeds, and over bumps. Listen for suspension noises. Test braking (no pulling, no vibration). Check steering play. The test drive should be at least 15 minutes.

11.
Check the service history

A complete service book with dealer stamps adds value and trust. Gaps in service history between 60,000–120,000 km are suspicious — this is when expensive services (timing belt, clutch) are due.

12.
Review the registration documents

Verify the seller’s name matches the registration. Check how many previous owners there are. Frequent ownership changes in short periods can indicate problems the seller discovered after buying.

13.
Check for outstanding finance

In some countries, a vehicle can be sold while still under a finance agreement. If the seller defaults, the finance company can repossess the car from you. Ask for proof of settlement.

14.
Get a professional inspection

For vehicles over \u20ac5,000, consider a pre-purchase inspection by an independent mechanic. This typically costs \u20ac100–200 and can save you thousands. Many mechanics offer mobile inspection services.

15.
Negotiate with data

Use the VIN intelligence report, identified issues, and market value data to negotiate. Every open recall, worn tire, or service gap is a negotiation point. Data-driven negotiation typically saves 5–15% off the asking price.
