@lowrider57 Thank you so much for the information. I forwarded your questions to the seller - translated to german, though. :)
The hinges and the cover are fine, as far as the seller states. I hope "completely new adjusted" is about the suspension.
Can you advise me on how I can check for speed control? I think I heard something about strobe discs?
Anyway, I will let you know about the seller's feedback.
