Hello! I sold my car privately. An Opel Astra with 109Tkm. After 4 days or 33km the buyer stopped with a clutch damage on the highway. She claims I should have known about the problem but also with me and during the test drive he ran still without problems. I myself have renewed the clutch at 51Tkm so the clutch has only 58Tkm on it. The car was sold without warranty and warranty. Am I to blame?
