Why so expensive

Want to exchange for my FJ cruiser toyota 1:32 scale 1:18 bburago range rover and 3+ other more small cars 1:32?

It is now worth far more than it was originally sold for because of its rarity.

You can also try joining die cast collector groups. Someone might be interested to swap or sell.
