The Beset of the Best
The level of care, kindness, and respect that Tyler Reynolds showed to my wife and I was unlike anything we have experienced at any dealership. Every other person of the Sewell staff was no different. I have always heard great things about Sewell dealerships and we were not disappointed. We worked with Matthew Jobe on the finance end and he was fantastic as well. Both Tyler and Matthew from start to finish provided us a true no pressure deal. I’m convinced that Sewell Buick GMC wants what’s best for my family and budget. It almost feels wrong to say that I really enjoyed the car buying experience at a dealership but it’s the truth. I want to make sure and add that the care and help did not stop when I drove off the lot. Tyler and Matthew have answered every question quickly and professionally since we have had the car. All that being said, my family will never buy from another dealership. These two men have made us Sewell customers for life.
