Our Reviews
Jerry Pena was ABSOLUTELY AMAZING!! He did not judge a book by its cover, my husband went in his work clothes and boots, Jerry was about to take lunch and helped him get our dream truck! Thank you, Jerry, for making this processed super easy, time saving and transparent! We are so happy with our new truck and will be back for mine soon! Thank you a million!
We had a wonderful experience. Mario was professional and friendly and it really felt like he just bent over backwards to get us everything that we needed and everything that we wanted. we left in good spirits. Extremely satisfied with the customer service. I would definitely shop here again.
So my GMC app alerted me that I had a recall so I made an appointment last week for today. Got there right at 8am. Mr. Avo came out and let me know it might be 3 hours. I was dreading the wait cuz I have major back issues. But the waiting area had softer chairs that made it comfortable for me. 2 hours later Avo calls me and says come meet me outside your truck is done. 2 recalls fixed, oil change done, tire rotation done and point inspection done. Thank you also to any and all mechanics that worked on my truck.
Jerry was an excellent sales person and very helpful with the entire process. Great experience
