They fixed a couple little dents for free, Toronto was very good to deal with, I would recommend going through these guys if you are in the market for a new or used vehicle.

Vanguard Buick GMC of Carrollton review

Had a great experience there hassle free. Jermey Burrell had everything laid out for me when we got there. I would recommend to anyone. Keep up the nice work.

2026 GMC Sierra 1500 AT4 review

A little expensive, but comfortable, quiet, smooth ride.

A little expensive, but comfortable, quiet, smooth ride. Great performance out of the 6.2L and better than expected fuel economy in the low 20s. Outstanding interior and good looking exterior, especially in the Downpour Metallic color. I don’t have 700 miles on it yet and have owned it for 3 weeks. Therefore, I can’t pass judgement yet on the reliability, but so far I am very satisfied. This replaced an 8 year old Ford F150 that served me quite well with only a couple of issues in the 100,000 plus miles.

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

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!
