Robbie, my salesman, was outstanding!! He made it painless and is absolutely customer focused. Pricing was ultra-competitive. Dealership was clean. We will definitely go back.

Bought my car here and have it serviced here never felt sold very happy with my purchase?the family is loving the new vehicle it rides super smooth

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.

Went in for an oil change?the process was quick and smooth. Really appreciated the excellent service. Big thanks to Elliot for taking care of everything.

This was the best car buying experience i ever had! No haggling, no waiting for hours, great salesman, and fast financing. Everything explained thoroughly. I was recommended to this dealer and will recommend to anyone shopping new or used. AAAAAA

Staff was very professional and helpful. Truck was priced as advertised. I received a fair value for my trade in.

A very pleasant and help full service writer. They provided necessary repairs in a professional manner. I have been using McKinney Buick since purchase five years ago. I am very satisfied.

Very good and courteous staff. Had difficulty locating my appointment but all went smoothly afterwards. Picked up my car in no time. It is always washed for me!

We had a straightforward, no hassle, seamless car buying experience at Ewing. Our salesman, Clayton, made the entire process easy for us from trading in our ?problem vehicle? to finding us the exact car we were looking for and having it delivered promptly. There were no salesman tricks, no hidden fees and no pushes to purchase extras we didn?t need. All around great experience. Highly recommend!

My second vehicle from this dealership. My second Buick Enclave and it keeps getting better.

After searching for over a year for the right truck, I made several unannounced, walk-in visits to Ewing GMC in Plano. Every single time, Josh Manning and Clayton Hass were exceptionally responsive and professional. Even without appointments, they made sure I was fully taken care of?quickly, courteously, and without any pressure. Their communication was clear, follow-through was flawless, and they consistently respected my time. In an industry where service can be hit or miss, Josh and Clayton set the standard. They are a true asset to Ewing GMC, and I highly recommend

Great experience, I was nervous to purchase a new vehicle but Aaron got me into exactly what I wanted. Friendly, personable staff helped me into the best loan and I was able to drive home in my new car a couple hours later!

Excellent service just completed on my Enclave with fast turnaround. The car was returned cleaned inside and washed outside, a very nice bonus. I'll use Ewing for the next service and or repairs!

I have purchased cars from Sewell in the past and once again, their service and inventory is SUPERIOR! We are so happy with our vehicle and the overall experience!

The best used car deal I have ever made. First time buying with Sewell and had a great experience.

Jarrett Abel has been my Service Adviser for several years. He always takes care of scheduling my appointments and getting my Chevy P/U serviced. The service department does a terrific job of getting vehicles serviced quickly.
