Friendly, hard working staff.
Friendly, hard working staff. Kline was professional and personable. Kline is the MAN! John was also very friendly and flexed with his ability to get me financing. Niko was also a pleasure to deal with. Overall a seamless and painless deal. We never felt pressured but we did feel welcomed. Everyone was very friendly. We would gladly make the drive up from Brighton, CO again.

It was by far the best experience of purchasing an automobile I’ve ever had. Very courteous and helpful. I actually went to GMC dealers in Va. and NC and they couldn’t help me get the SUV I wanted. Went to Cars.com and submitted 3 notice of interest to 3 different dealers and Zeigler responded within 5 minutes. No haggling and gave me a more than fair quote. Everything went smooth and finally heard from other dealers an hour or two later. Really appreciate the professionalism. Love my truck and it was delivered today! Thank you for all your help.

Findlay Chevrolet GMC, Bullhead, AZ.
Findlay Chevrolet GMC, Bullhead, AZ. I had an excellent experience at Findlay Chevrolet GMC. Salesperson Alex Bird was professional and knowledgeable about Chevrolet and GMC products. I was there for only a couple of hours and left in my new GMC. The facility was clean, and all employees were professional and respectful, which is remarkable in these divided times in America.

Exceptional Service and Experience!
Exceptional Service and Experience! I had an amazing experience at Lake Chevrolet Buick GMC. From the moment I walked in, the entire team was incredibly welcoming, professional, and genuinely helpful. They took the time to listen to what I was looking for, answered all my questions without any pressure, and made the whole car-buying process smooth and stress-free. Dave Brustad in particular, went above and beyond to make sure I was comfortable and confident with my decision. He was knowledgeable, patient, and truly cared about finding the right vehicle for me. I couldn’t be happier with my purchase and the outstanding service I received. If you’re looking for a dealership that treats you with respect and puts your needs first, I highly recommend Dave at Lake Chevrolet Buick GMC
