Cupra 300 SC BJ18 when to sell/repel?

Hello dear Leon municipality, I bought a Seat Leon Cupra 300 in January for 33000 Eurons with 15 km of daily admission. The good piece would be after 4 years of running completely and even mine. Now, of course, that’s how many people say one should repell such cars (so in general all those in the “Class” of the Cupras so 2L 300 PS cars ) at some point again. Be it because of possible problems after the warranty (motor, gearbox, turbo and much more) and also because of the value reliability My plan was to sell the car just before the end of the 4 years of financing itself. However, I have heard and read that it would be advantageous to sell it before reaching the 40tkm brand all about it would be financially unchalant. I had looked on the internet for how much so people offer the car and thought jo for 20000 thousand euros people offer the cars with 70tkm to 80tkm, well then the value loss is quite ok. Many say however: yes the offers si And so nobody does it. That’s why the question arises from when should I reject it, so with what mileage I will get rid of it well again or get it sold worth 15k to 20k. I thought then 70tkm to 80tkm would be inside, but apparently it’s not like that. I hope some can help me further and share their experience or opinion on what would be the smartest.
