A car purchase has three parts: checking what you are buying, agreeing what each side promises, and exchanging the money and car safely. A careful inspection and a clear written contract can prevent a small omission becoming an expensive dispute. Sellers need those protections too.
This guide covers ordinary car purchases and private sales in Germany, with a focus on used cars. Leasing, business purchases, imports and cross-border sales can need different checks. Whether the seller is a business or a private person changes your rights. The consumer-defect rules below describe purchases under current law; contracts made before 1 January 2022 need the earlier rules checked (Article 229 § 58 EGBGB).
1. Buying: inspect before agreeing
- Budget beyond the price. Include insurance, vehicle tax, registration, maintenance, tyres and likely repairs. Compare finance offers using the total repayment, interest, final instalment and any linked insurance.
- Check the seller and the vehicle. Compare identity, contract details and the vehicle identification number (VIN) with the car and original registration documents, Zulassungsbescheinigung Teil I and II. If someone sells for the owner, ask for evidence of authority. Part II alone does not prove ownership; ask whether finance or another person's rights still affect the car.
- Read the history. Request service records, repair invoices, the latest Hauptuntersuchung (HU) report and details of accident damage. Compare recorded mileages. A valid HU is not a guarantee that the car is defect-free.
- Inspect and test drive. Look for warning lights, leaks, rust, uneven tyres and signs of repair. Agree insurance and liability for the test drive first. For an electric car, ask for a battery-health report, charging equipment and remaining battery-guarantee terms.
- Get an independent inspection. A mechanic or vehicle expert can identify problems a contract review cannot. If the seller refuses reasonable checks or pressures you to pay immediately, pause the purchase.
ADAC's used-car resources provide inspection and buying guidance. Save the advert and messages before they disappear.
2. What belongs in the contract
Use a written agreement suited to the actual sale. A private-sale template should not be used to disguise a business selling to a consumer. Fill every relevant field, cross out unused spaces, and give both parties a signed copy. Writing is recommended as evidence: an ordinary car-sale contract can also become binding orally. Do not assume you are uncommitted merely because nothing is signed.
- Names and addresses, the actual seller, make, model, VIN and registration number.
- Price, payment method, any deposit and the agreed collection date.
- Displayed mileage and any separate promise about total mileage; these are different statements.
- Known accidents, repairs and defects, written specifically rather than described as “usual wear”.
- Included keys, documents, accessories, tyres and any promised repair before delivery.
- Any guarantee, defect-liability terms and arrangements for deregistration or re-registration.
Put important promises into the agreement, especially “accident-free”, a particular specification or a repair the seller will carry out. Do not sign wording saying you are buying as a business when you are purchasing privately. There is no general 14-day change-of-mind right for a purchase at a dealership or from a private seller. Some distance or off-premises consumer contracts have withdrawal rights; an online advert alone does not establish one. See the contract cancellation guide.
3. Selling: disclose and document
Describe the car accurately and disclose known faults and accident damage. If you cannot verify the total mileage or earlier history, say so rather than making a promise you cannot support. Keep the advert, inspection records and signed agreement. If the car is financed or leased, establish your right to sell and arrange release with the lender or owner before promising delivery.
A private seller can generally agree to exclude statutory defect liability, subject to the wording and legal limits. “Private sale” or “no returns” alone should not be treated as a complete exclusion. Under § 444 BGB, an exclusion cannot protect a seller who fraudulently conceals a defect or guarantees the relevant condition. A general exclusion also does not normally override a specifically agreed condition of the car. The Federal Court of Justice confirmed this in VIII ZR 161/23 (10 April 2024). Standard-form clauses have additional limits, including for personal injury and gross negligence (§ 309(7) BGB). Obtain advice on unusual terms rather than inventing a blanket disclaimer.
4. Payment, registration and handover
Agree a payment method both sides can verify. A transfer screenshot or email is not proof that money has reached the seller's account. Check receipt independently before releasing the car and original papers. Buyers should avoid sending money to an unknown seller before checking the car and the seller's authority. Treat unexpected escrow links, overpayments and requests to refund a third party as warning signs.
Record the handover date and time, mileage, condition, payment receipt, keys and documents in a signed handover record. Arrange whether the car will be deregistered before collection or re-registered together. For a registered vehicle, the previous keeper and owner must notify the registration authority without undue delay unless the buyer has already completed the required re-registration. The buyer must also re-register without undue delay (§ 15(5) FZV). The sale must be notified to the insurer by the seller or buyer without undue delay (§ 97 VVG). Keep evidence; a buyer's promise to re-register does not remove every practical risk.
Before driving away, check registration, number plates, insurance and roadworthiness. Buyers normally need an electronic insurance confirmation (eVB), identity documents, registration papers, HU evidence and vehicle-tax payment arrangements; check the local Zulassungsstelle's current list, such as Berlin's re-registration requirements. Old plates alone do not authorise driving a deregistered car. There is a limited exception for a return journey on the previously assigned plates until the end of the day of deregistration, if liability insurance covers it (§ 12(4) FZV). Confirm that the intended journey qualifies; otherwise arrange lawful registration or transport. ADAC explains registration, sale notifications and limited exceptions for journeys after deregistration.
5. Dealer purchase or private sale?
For a consumer buying from a business, statutory defect claims generally run against the seller. A Garantie, whether included or paid for separately, is additional cover with its own conditions; it does not replace Gewährleistung (§ 443 BGB). The ordinary limitation period is two years from delivery under § 438 BGB. For used cars it can be shortened to at least one year only with specific advance information and an express, separate agreement under § 476 BGB.
A defect appearing within the first year is generally presumed to have existed at delivery in a consumer sale, subject to exceptions and rebuttal (§ 477 BGB). Normal wear, a disclosed and validly agreed departure from the expected condition, or damage caused later is not automatically a seller's responsibility. Age, mileage and the agreed condition matter.
Private sales do not have these consumer protections, and a valid liability exclusion can substantially limit claims. If a dealer says it is selling “on behalf of a customer”, establish who the contractual seller really is. The label alone does not settle whether the business is trying to avoid consumer law.
6. Common problems and the next step
- A fault soon after purchase. Stop driving if safety is affected. Record symptoms, mileage and dates; notify the seller in writing and ask for a remedy. Usually give the seller the opportunity to repair or replace before commissioning repairs elsewhere. Agree transport for an unsafe vehicle.
- Hidden crash damage or suspicious mileage. Preserve the advert, promises, service history and an expert's findings. A mismatch needs investigation; it does not by itself prove fraud. A lawyer can assess contractual claims and whether there is evidence of deliberate deception.
- The seller refuses or repairs fail. A price reduction, withdrawal or damages may become available if the requirements are met. A refund is not automatic, and there is no universal requirement to accept two repairs in every consumer sale. See § 475d BGB and the faulty-goods guide. An insignificant breach does not justify withdrawal (§ 323(5) BGB).
- Missing papers or outstanding finance. Before buying, establish the document and release arrangements. If already bound by a contract, ask for advice on whether payment can lawfully be withheld rather than simply missing a due date. If already paid, seek advice promptly about ownership and recovery.
- Fake payment or a disappearing seller. Contact your bank quickly, retain messages and account details, and report suspected fraud to police. A police report does not itself recover the money or preserve civil deadlines.
- A buyer complains after a private sale. Ask for the fault, evidence and requested remedy in writing. Check the contract and your disclosures; do not assume every complaint is valid or that every exclusion is effective.
Report problems promptly. Notification alone does not necessarily stop limitation running. Consumer rules can extend periods, including a one-time twelve-month extension following statutory repair for contracts concluded from 31 July 2026 (§ 475e BGB and Article 229 § 72 EGBGB). Have the dates checked rather than assuming every claim expires after exactly one or two years. For those newer contracts, before providing a statutory remedy the business must explain the repair-or-replacement choice and the repair-related extension (§ 475(4) BGB).
7. When a lawyer can help
A lawyer's review can be useful before a high-value purchase with unusual terms, unclear ownership or a disputed dealer/private-sale arrangement. After purchase, seek help for expensive defects, alleged deception, failed remedies or a deadline approaching. An inspection assesses the vehicle; legal review assesses the promises and available remedies.
Send the contract, advert, messages, delivery date, inspection reports, repair invoices and a short timeline. Ask for the proposed scope and fee before commissioning work. You can request an English-speaking consumer lawyer for a car-purchase dispute; if you are selling privately, describe that clearly.
