Hello Together, my Mercedes will be 30 years old next month and should, if everything goes well, get the H-mark. I still have a few ambiguities like the procedure after the review by the Tüv. – If H-marks are assigned then I just go to the registration office and have new signs made and ready? – Does the insurance still have to be informed? Am currently at the ADAC in the classical insurance. Greetings Markus
