I have 2 svart and I love this bike, but you need to consider:
This bike does not sell in the UK, and after the KTM difficulties, they were selling the 2023 version at £3150 NEW.
Unfortunately, I don't think you can sell it for 3k. Dealers around are offering £1000, or they're not even taking it as a trade-in.
Realistically, if you want to sell it as a private around 2k, it can be done, as the 2019 was still made in Austria and the build quality is better.
On Facebook, I can see them around 1700 to 2300, and they are not flying off the shelf.
Sorry for the bad news
