Repairing or selling galant due to TÜV?

Hello, I wanted to ask you for your opinion on what you would do: I have the following vehicle (see end posting) (as I have already posted before), where the TÜV/AU is due and there are some repairs to be made. If I have this repaired as a non-screw and plan a few more unforeseens I will get rid of an estimated 1000 EUR. If I reinset the intact car at Autoscout24 I can expect 4500-5000 EUR, I think!? Is it realistic to untouch the vehicle? The fact is that I am going to buy a new vehicle in April. In principle, it doesn’t cost me anything to test it out and advertise it at as24. But what should I get involved with and what should I not do when offers come? I just don’t want to start repairing it and putting in expensive money if I don’t see the money in any way (compared to the unrepaired sale). What would you do? What is easier: A rep Needed to buy a car at a low price or a repaired intact car at a high price? What to keep from such export buyers who advertise in the forum of as24.de with maximum prices when buying. Does in some cases very dishonest, because only mobile phone number. But if the price is right? Thank you and greetings, Heiko Here are the vehicle data: Mitsubishi Galant EAO 2.0 Automatic Lim.
