Sewell Buick GMC of Dallas review
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.

Brandon Tomes Subaru review
Extra-ordinary Maverick Roger Venegas and team
I leased a Subaru Ascent limited edition 2023 model last week. I had the pleasure of working with Roger Venegas, Sales Professional at Brandon Tomes Subaru. He is one the best sales person i have come across. He understood my needs, was caring and guided me on the sales process, was very transparent and worked very quickly on the sales process. I thoroughly enjoyed working with Roger who is an extra-ordinary sales person. The manager and finance person were also equally good. It is a life a family at this Car dealership. These people do not sell car, they sell and maintain relationship with customer. I strongly recommend this showroom.

I left a google review bc overall I've been pleased with your body shop and service department! Love the popcorn, cookies, and snacks. I felt very welcome, wonderful dealership. I've always been a Sewell customer bc of their customer service, but y'all exceeded my expectations and now I want to be a life long Ewing customer. We had a few communication issues between the body shop and service dept the other day, but other than that, very happy! Thank you so much, to Tag and Dan!
