Question juridique clé
Whether the buyer could invalidate the car sale for fraud instead of relying on warranty claims.
Solution extraite
The buyer was entitled to rely on invalidation for fraudulent misrepresentation; no ratification of the contract was established.
Motifs extraits
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.
