Is it true that Most people pay with bank Transfer on Leboncoin?

I'm in the process of buying Something and having it shipped to germany. The seller doesn't want leboncoin's payments system, as the fees and waiting time to receive the money are high. He also doesn't want to use PayPal with protection, as I can just refund the money no matter what. He Claims, that a simple bank Transfer ist the best and is normally used in france. Is that true?

I feel conflicted, as I don't have a Chance to get my Money Back in Case Something aint right. He also Claims He has to wait days to get it payed out and needs to "Report it" (to whom?) If payed with PayPal goods & Services. He prefers PayPal Friends or Transfer.
