Why Old Cars with 200,000KM+ So expensive Here ?

Recently I started thinking about Buying my first car in Portugal, maybe a Toyota Yaris body type, city car and to my surprise they look super over valued, because last time I checked in 2019, the same cars were being sold for let's say 1,500 to 2,000 max, but now same cars are being sold for 3,500+

I mean Math i not Mathing, even if I account for the recent post C19 inflation.
