Vehicle sold – car rental characteristics

Hello, I sold a car last week to a dealer. He got the car and gave me the money. I paid for the still open financing with the money. Now the letter arrived at me by mail and as a previous owner is “euprove car” Is this now a problem where the dealer can stand a rope out of it? When buying the car nothing was mentioned by the previous owner. So I didn’t say anything about it (except 2 previous owners) Thanks for your Antwor The Commission’s proposal was adopted by the Council on 19 December.
