600 Euros or nothing

The seller of this SCALEXTRIC EXIN 4054 TYRRELL P 34 BANCO OCCIDENDAL has refused to sell it for 600 Euros. Of course, this is rare slot car from the 80', in excellent condition, and the seller consider it is worth it. The problem is that, even if this 6 wheels F1 model is rare, it is not part of the most desirable cars collectors are looking for to complete their Ferrari, GT 40 or Aston Martin's collections for instance. It is one of a kind, that's all. So the seller probably made a mistake, because 600 euros is already a very good price very few slot cars collectors can afford to pay.
