Kernrechtsfrage
Whether the buyer could invalidate the car sale for fraud instead of relying on warranty claims.
Extrahierter Entscheid
The buyer was entitled to rely on invalidation for fraudulent misrepresentation; no ratification of the contract was established.
Extrahierte Begründung
The record did not show that the buyer invoked warranty remedies or otherwise clearly ratified the sale; continued use of the car after discovery did not, by itself, amount to ratification.
