Vehicle sales: HU/AU will be due next month / what to do?

Hello, unfortunately there is no sales consultation forum, so I try it here. I want to sell my 11-year-old Skoda Fabia. HU/AU is due in the Jni. Now I wonder how I best proceed:Option 1: Cars try to sell like this. I have no idea what else to do so that HU/AU is renewed and can thus not give the buyer any details about it. Will the vehicle take such a person at all?Option 2: I leave a cost charge in a workshop Creating what needs to be done for HU/AU. However, I do not let this happen, but only share what needs to be done with the potential buyer and what it will cost. Option 3: I try to bring the car over to HU/AU. If defects are detected, see option 2. I am really completely unsure which way is most useful. I would be very pleased about feedback.
