I have seen similar thing to happen in Finland for older cars:
- Toyota Corolla, 2005, new Toyota radio from the dealer 1200€, used from the junk yard 200€
- Nissan Primera, 2006, new Nissan PCV valve from the dealer 90€, used from the junk yard 10€.
My theory for these insane prices is that maybe EU mandates the dealers to keep OEM parts available for consumers for example for 20 years. And as the parts become rare for obsolete cars, the dealer sets prices so high that they can be sure that the last few parts stays on their shelves until that mandated 20 year is reached. I call them ”intended no sale prices”, and all of a sudden those high prices do make a lot of sense.
