This morning, the SLK 230 brought my girlfriend to Mercedes. The disc didn’t close properly. It didn’t go into the seal, but outside the seal. Thought the men of Mercedes could fix the disc again. Daimler’s seriveman later said to my girlfriend that it could also be due for a new disc; but he called it before. It came as it had to come: He called me friend earlier; something was about the SK 230. They had to do everything new – invoice 340 euros. Of course they had not asked before! You wanted to show us the broken parts this evening. I now have a thick neck, because they can tell me a lot. The disk itself was not broken. what can they have repaired/changed for 340 euros – however -?! Thought that was only a matter of setting the disk – and now such a rech This evening I will tell them something, but I don’t want to show up there completely unprepared. Therefore my question: what could have been so bad about the window/door that justifies such a bill? Thank you for quick help!
