Haaaaallo friends, I’ve been really trying to get some information. Unfortunately, I didn’t find anything, maybe because I used the wrong key words. The following question: I have an old car with an H mark (petrol with green badge) and I want to do something. Sport auspuff, maybe a spoiler, not contemporary rims etc. I know that I should actually do a contemporary tuning at Oldtimer. Only here comes the point. Get i ch trozdem Tüv ohne H Kennel despite not contemporary tuning ? I don’t care (at the moment) the H license plate since I can ride with green badge quite relaxed in the inner city and outside anyway. As soon as I needed it again (unlikely) I would put the old things back on. lg
