This my second time buying from Partspionner.ca great parts quality parts fast shipping to your door no need to wait on parts counter for minutes save gas ;)
I had an excellent experience ordering from Parts Pioneer, my order was placed and shipped quickly and received. Excellent customer service, I will definitely use them again when needed and let many of my friends know about Part's Pioneer
The site was very easy to use. When I emailed with a question the response came quickly. I appreciated that you verified that the parts would fit my vehicle. I will use the site again.
La livraison se fait en un temps record, malheureusement il y a eu un erreur de pièce, par contre un service très professionnel, facile d'accès et dans ma langue natale..... 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... Merci à l'équipe
Toujours en attente du ticket de retour mais j'ai confiance dans leurs bref délais...
