Sewell Cadilac of Dallas was Outstanding.
Sewell Cadilac of Dallas was Outstanding. They treated us like an old friend. The whole experience was pleasurable and quickly handled over the phone. All of the details and paperwork was done when we arrived. They took time to explain all of the new vehicle's controls, features and warranty issues. It took about 5 minutes to sign the paperwork on the purchase and we were on our way. i

We had a straightforward, no hassle, seamless car buying
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!
Nicest, best performing truck I've ever owned
My truck has a great appearance, inside and out. It is a pleasure to drive; and rides and performs great. It is the best truck I've ever owned.

I have received nothing but great customer service from
I have received nothing but great customer service from Caleb and the Corvette service team at Stonebriar Chevrolet on my 2025 Z06. From oil changes, installing Srape Armor protection and inspections after trips. I highly recommend the Corvette team at Stonebriar.
2021 GMC Sierra Denali
This is the nicest truck I have ever owned. Lots of features. Takes a while to learn what all it does but a really enjoyable vehicle.
