Used car buying checklist
What should I check before buying a used car to avoid getting scammed?
Projekt-Plan
Why: Used cars often require immediate small repairs or fluid changes after purchase.
How:
- Set a hard limit for the purchase price.
- Add 15% on top for registration fees, immediate service (oil/filters), and potential surprises.
- Factor in monthly costs like insurance and fuel.
Done when: [Total budget and purchase limit are written down]
Why: Avoid models known for frequent failures to minimize long-term costs.
How:
- Look for top performers like the Honda Jazz, Mazda 2, or VW Golf Sportsvan.
- Be cautious with low-performers like the Tesla Model 3, Dacia Logan, or older Ford Mondeo models.
- Focus on 'Significant Defects' rates for cars in the 5-7 year age bracket.
Done when: [List of 3-5 reliable target models created]
Why: Insurance costs vary wildly based on the specific model's accident statistics.
How:
- Use a generic insurance comparison portal.
- Enter the HSN/TSN (manufacturer/type numbers) of your target models.
- Compare the annual premium for liability vs. partial/full coverage.
Done when: [Annual insurance cost for each target model is known]
Why: Dealers provide a mandatory 12-month warranty (Sachmängelhaftung), while private sales are 'as is'.
How:
- Search on platforms like Mobile.de or AutoScout24.
- Prioritize dealers with high ratings if you want safety.
- Choose private sellers for better prices, but only if you are confident in your inspection skills.
Done when: [3-5 concrete vehicle listings identified]
Why: Prevents buying stolen vehicles, 'title-washed' cars, or those with hidden total-loss history.
How:
- Ask the seller for the Vehicle Identification Number (VIN).
- Use a service like Carfax or AutoCheck to pull the history.
- Check for mileage inconsistencies and previous accident records.
Done when: [Clean history report obtained for the favorite candidate]
Why: A 'gapless' service history (Scheckheftgepflegt) is the best indicator of a well-maintained car.
How:
- Check if services were done at recommended intervals (usually every 15k-30k km or annually).
- Look for stamps from authorized workshops.
- Verify if the stamps look suspiciously identical (same ink/pen), which could indicate forgery.
Done when: [Service history confirmed as plausible and complete]
Why: Uneven gaps are a primary indicator of past accidents and poor repairs.
How:
- Check the gaps between the hood, doors, and trunk.
- Compare the left side to the right side; they must be identical.
- Look for 'overspray' on rubber seals or plastic parts, indicating a cheap repaint.
Done when: [Body confirmed as straight and original]
Why: Detects hidden body filler (Bondo) used to cover up rust or dents.
How:
- Wrap a small magnet in a soft cloth to protect the paint.
- Run it along the wheel arches and lower door panels.
- If the magnet doesn't stick, there is thick filler underneath.
Done when: [No hidden filler detected on critical panels]
Why: Detects odometer fraud (mileage rollback).
How:
- Check the brake pedal rubber; if it's worn through but the car shows only 40k km, the mileage is likely faked.
- Inspect the steering wheel texture and driver's seat bolster for excessive shine or cracks.
- Check for 'oil change' stickers in the engine bay that might show higher mileage than the dash.
Done when: [Interior condition matches the odometer reading]
Why: Old or worn tires are a safety hazard and an immediate €400-€800 expense.
How:
- Find the DOT code (4 digits) on the sidewall; e.g., '2224' means week 22 of 2024.
- Tires older than 6 years should be replaced regardless of tread.
- Ensure at least 3mm tread depth (legal minimum is 1.6mm, but unsafe).
Done when: [Tire condition and age documented]
Why: Many engine issues (rattling chains, smoke) only appear when the engine is completely cold.
How:
- Touch the engine block before starting to ensure it's cold.
- Listen for metallic rattling (timing chain) in the first 3 seconds.
- Check the exhaust for blue smoke (burning oil) or thick white smoke (head gasket).
Done when: [Engine starts smoothly without unusual noises]
Why: Sellers often clear error codes (Check Engine Light) just before a viewing.
How:
- Plug a generic OBD-II scanner (e.g., ELM327) into the port (usually under the dash).
- Use an app like Torque (Free) or Carly to check for 'Pending' or 'Permanent' codes.
- Check 'Readiness Monitors' to see if codes were recently deleted.
Done when: [No critical error codes found in the system]
Why: Identifies warped rotors, worn suspension, or alignment issues.
How:
- Drive on a straight, flat road and briefly let go of the wheel; the car must stay straight.
- Brake firmly from 50 km/h; the wheel should not vibrate.
- Turn the wheel fully to both sides while driving slowly to listen for clicking (CV joints).
Done when: [Test drive completed without vibrations or pulling]
Why: A written contract is your only legal protection against fraud.
How:
- Use a generic template (e.g., from ADAC or Mobile.de).
- Ensure the phrase 'Gekauft wie gesehen' (bought as seen) is only used in private sales.
- Explicitly list known defects and the total mileage.
- Verify the seller's ID matches the name on the vehicle title (V5C / Zulassungsbescheinigung).
Done when: [Contract signed by both parties]
Why: Cash carries risk, and wire transfers are untraceable in scams.
How:
- Use a Real-time Bank Transfer (Instant Payment) while standing next to the seller.
- Alternatively, use a Cashier's Check or meet at the seller's bank.
- Never use Western Union, PayPal 'Friends & Family', or unverified escrow services.
Done when: [Payment confirmed and receipt obtained]
Why: You cannot legally drive the car until it is registered in your name.
How:
- Obtain the eVB number (electronic insurance confirmation) from your insurer.
- Book an appointment at the local registration office (Zulassungsstelle).
- Bring the Title (Part I & II), your ID, and the eVB number.
Done when: [New plates mounted and registration complete]
Why: Missing the deadline leads to fines and loss of insurance coverage.
How:
- Check the round sticker on the rear license plate for the year and month.
- If the deadline is within 3 months, book an appointment at a generic testing station (TÜV, DEKRA, GTÜ).
Done when: [TÜV date is noted in your calendar]
Why: Driving with wrong tires increases fuel consumption and reduces safety.
How:
- Follow the 'O to O' rule (October to Easter) for winter tires.
- Check if the car came with a second set of wheels.
- Store the off-season set in a cool, dry place or at a professional 'tire hotel'.
Done when: [Seasonal tire change scheduled]
