I recently took my Canyon in for repairs.
I recently took my Canyon in for repairs. Myriam was my point of contact, she was awesome with her communication and updates. My truck had to stay due to parts not in stock, she provided transportation to and from her location. This is the reason why I have purchased my second vehicle with GMC North.
