Z flip 6 Leboncoin paris

Hello everyone, I sell the Z flip 6 in Paris and often people who are interested in my ad find it expensive. I put it at 660 € and each time they want to buy it for 400 to 500. Except that for me it's much too low. Knowing that the phone is barely 6 months old or not even then. Do you really think it's too expensive or do I only come across people who are big rats?
