leboncoin escrow service for used cars

Hi

I´m looking for opinions about this service, I believe it´s called "Le Paiement sécurisé"

I have read the theory on their website but now looking for the experience.

The used vehicle I am looking to buy costs around 40K. It´s in France and I will register it in Spain.

And one specific question: considering I would be visiting the seller and checking the vehicle myself, what would be the advantages of the service Le Paiement sécurisé ?
