Le retour est accepté sans frais. Tout les professionnels dans le domaines de la mécanique savent que des erreurs survient aléatoirement au niveaux pièces un jour ou l'autre, pas très agréable mais la ou ce joue la qualité du service est le service après vente et je peux confirmé la compétence de l'équipe Parts Pionner...
