J’ai appelé pour savoir s’ils avaient une pièce en stock, et malheureusement ce n’était pas le cas. Cependant, le monsieur au téléphone était vraiment hyper gentil, a pris le temps d’écouter et me conseiller. Si j’ai à nouveau besoin un jour, je me dirigerai à nouveau vers eux !

Franchement je vous recommande konexauto, c'est un peu plus chere que si vous commandé de votre coté mais le point fort qu'il faut retenir c'est que déjà il vous commande les pièces donc normalement c'est 99% que c'est la bonne pièce, les pièces sont de bonne qualité et en plus de sa, les pièces arrivent le lendemain. Merci pour votre service de qualité.

Honestly, I recommend Konexauto. It's a bit more expensive than ordering on your own, but the main advantage is that they order the parts for you, so there's a 99% chance it's the right part. The parts are good quality, and on top of that, they arrive the next day. Thank you for your excellent service.
