Purchased car was scrap

Hello, I would have a question. I bought a Ford Escord Combi Built 1995 in June last year, with a one-year warranty. Now I learned from my workshop that this car was already scrap at the time of sale, because all the sleepers are rusted through, which was not apparent when buying it, because it was well leased.The car at the time also got TÜV. Can I now proceed against the dealer afterwards, because of false facts or something like that?????
