The story: a second-hand Seat and a report nobody read
The buyer purchased a used Seat Leon from a private seller for 6,400 euros. The contract stated a mileage of 111,000 km. A year later he decided to sell the car on. He showed the interested party a roadworthiness-test report (in Germany issued by TÜV, DEKRA and similar bodies), which he had received together with the car. And then — only then — someone actually read that report.
The report showed that seven months before his purchase the car had already clocked 197,744 km. Almost 90,000 kilometres more than the odometer showed on the day of the sale. The buyer demanded 1,600 euros from the seller, because that is how much less the car would have cost with its true mileage. The case went to court.
It looked like a won case. It ended in defeat
The court dismissed the claim. Not because the odometer had not been tampered with — that was essentially certain. The buyer lost because he could not prove that it was the seller who rolled the odometer back, or that she knew the true mileage.
The seller maintained that she herself had bought the car showing 108,000 km — and produced a photo of the odometer taken on the day of her own purchase. The previous owners, heard as witnesses, remembered next to nothing two years on. Their answers ran along the lines of: could have been 108,000, could have been more, I do not know. The court concluded that anyone in the chain of owners could have manipulated the odometer, and that the seller may have been deceived exactly like the buyer.
There was a second argument, too. The report with the true mileage had been handed to the buyer by the seller herself, together with the car. The court treated this as evidence of her good faith — someone knowingly hiding the mileage does not hand the buyer the very document that exposes it. And the fact that she never read the report herself? Under German law even gross negligence still is not deceit (§ 123 BGB).
Why the warranty exclusion held
The contract contained a handwritten sentence: “Privatverkauf ohne Garantie sowie Rücknahme” — private sale without warranty and without return. Such an exclusion between private individuals is in principle effective. It only falls if the seller fraudulently concealed the defect or gave a guarantee (§ 444 BGB) — and deceit could not be proven in this case.
And a second lesson that surprises many buyers: a mileage figure entered in a box of a contract form is, in a private sale, usually just information about what the odometer showed — not a guarantee that the mileage is true. That is how the court saw it in this case as well, in line with the settled case law of the Federal Court of Justice (BGH, judgment of 29 November 2006, VIII ZR 92/06). If you want a mileage guarantee from a private seller, you must insist on an express clause in the contract.
The exact wording of the contract and the listing matters enormously. The bare formula “gekauft wie gesehen” covers, according to the case law, only defects a layperson could spot on inspection — it does not exclude hidden accident damage, and it makes no difference that the seller himself knew nothing about it (OLG Oldenburg, case 9 U 29/17 — the buyer got her money back for a previously damaged Peugeot). And where the seller assured a specific quality in the listing, a warranty exclusion does not cover that quality at all — so the BGH in the case of a forty-year-old Mercedes advertised with “air conditioning works perfectly” (judgment of 10 April 2024, VIII ZR 161/23).
One more scheme to watch out for: a trader selling the car “on behalf of a client” to appear private and exclude the warranty. The Federal Court of Justice treats this construction as a circumvention of consumer protection where, economically, the true seller is the dealer — the decisive question is who bears the commercial risk of the sale (BGH, judgment of 26 January 2005, VIII ZR 175/04).
At a dealership the same case would end differently
The whole picture changes when the seller is a business — an Autohaus, a used-car trader. Against a consumer a warranty exclusion is ineffective, and a defect that shows up within a year of handover is presumed to have existed at the time of purchase (§ 477 BGB). It is then the seller who must prove otherwise. The mileage from the listing and the contract binds the dealer as an agreed characteristic of the vehicle (§ 434 BGB).
That is why the first question we ask in every odometer case is: who did you buy from? The burden of proof — and your realistic chances — depend on it.
Odometer tampering is a crime
Independently of the civil dispute, manipulating an odometer is a criminal offence in Germany, punishable by up to one year of imprisonment or a fine (§ 22b StVG). A criminal complaint can be a valuable addition to the civil track, because the investigation file may contain evidence the buyer could never reach alone.
Before you buy — and right after discovery
Before buying, ask for the report of the last roadworthiness test (HU) and compare the recorded mileage with the odometer — the buyer in this story held the proof in his hands for over a year and never looked at it. Check the service book and the history at a brand workshop. At handover photograph the odometer, make sure the mileage is entered in the contract, and from a private seller demand an express mileage guarantee. After discovering a manipulation, secure the reports and correspondence, identify the previous owners and do not resell the car with the false reading — you would expose yourself to liability.
What you can claim when the evidence is there
A rolled-back mileage cannot be “repaired”, so against a dealer the case moves straight to a price reduction or withdrawal from the contract — you return the car and recover the price, less compensation for the kilometres driven (§ 437 BGB). Where deceit is proven, you can also avoid the contract altogether (§ 123 BGB), and the claims become time-barred only after the longer, three-year general period (§ 438 (3) in conjunction with § 195 BGB). Against a private seller the routes are the same, but only once you show that he knew about the manipulation or carried it out himself.
That is exactly why odometer cases are decided by evidence and by choosing the right opponent, not by the statutes alone. The earlier they reach a lawyer, the more can be built out of them.
