Let's create a vehicle profile then

A little bit difficult. The vehicle was made for Hamburg but never delivered. The vehicle's official papers no longer exist - at least according to the auction site.
The vehicle dates from 2016 and was already partially dismantled by the factory. The minimum bid is only 2000 euros and no one has bid on it (until now, 24 hours before the auction closes).
The chances of this vehicle ever being put into service anywhere are minimal. The auctioneer explained in a newspaper that this kind of vehicle would only be useful for parts, but even here no one is interested...

Both buses were delivered: https://www.hamburger-fuhrparklisten.de/...ex.html
Even more! they already have profiles on the site:

Thanks for the research and corrections.
I don't know the exact details of what happened (in Hamburg). If anyone can clarify this, please!
As far as I have been able to find out, the order consisted of only 2 vehicles. Why they were sent back to the factory after +/- 1 year, I don't know.
The liquidator was unable to find a buyer for the two vehicles. The betting price was 2000 euros + taxes, but no one bid on them. Purely informative: many other buses and coaches were sold though, sometimes for high prices.
Both the vehicles are in a very poor condition. Given that this is a complex and lengthy legal matter and that the settlement of this bankruptcy may take years, I suspect that both buses will be rotting away on that property for years to come, unless the liquidator gives them to the new owner for free, who then has to incur the cost of disposing of them...
