Stinger value maintenance and second-hand market

At the moment I drive a Lexus IS-F and I have nothing to expose myself to. Unfortunately, I lived in the moment and didn’t look very far into the future and now that I want to continue my professional education but that would have to pay for myself because distance studies are the maintenance costs of Lexus already a brummer. Ultimately, I have already initiated a change to a Hyundai i30N fastback which gives me more space for my personal vehicle exchange. In the search for alternatives for the IS-F I also looked for the Stinger because it is in the same vehicle class, is cheaper in the maintenance and I always had a little interest in it and I was very surprised. There are already those that go away for less than 40,000€ as for example here or here. They are only about 1 1/2 old. That means in a few years Stinger could be almost incomprehensible bargains if you have the 7 years manufacturer But that also seems to mean that the concerns that some had when the car came out were probably appropriate in terms of maintaining value. That is ~30% value loss if you start from the EIA.
