The service advisor kept me in GMC. From the moment I pulled into the service bay, I was greeted warmly and treated with professionalism and respect. The service advisor kept me informed every step of the way and made sure all my concerns were addressed thoroughly. The technician working on my vehicle did an exceptional job—everything was completed ahead of schedule and my car feels brand new again. I also appreciated how clean and welcoming the lounge area was while I waited. This team truly goes above and beyond to make sure customers are taken care of. I’ll definitely be coming back to Alpine Buick GMC for all my future service needs. Highly recommend! More

I recently visited this dealership and was thoroughly disappointed by the experience. • Lack of Communication: Despite multiple attempts to reach out, my calls and messages went unanswered. This lack o disappointed by the experience. • Lack of Communication: Despite multiple attempts to reach out, my calls and messages went unanswered. This lack of responsiveness is unacceptable and unprofessional. • Inefficient Service: A simple tire change took over two hours to complete. During this time, I observed staff members engaging in inappropriate conversations about customers, which was both unprofessional and disconcerting. • Misleading Advertising: The dealership advertised vehicles at prices that did not reflect the actual cost. Upon expressing interest in a particular car, I was informed of additional charges amounting to several thousand dollars, far exceeding standard taxes and fees. This bait-and-switch tactic is deceptive and undermines customer trust. Overall, my experience was marked by poor communication, unprofessional behavior, and misleading sales practices. I cannot recommend this dealership to others and advise potential customers to exercise caution. More
