My scheduled service to replace tire and 5,000 mile
My scheduled service to replace tire and 5,000 mile service was in and out in great time for what had to be done. Service advisors had great customer service and made sure you were happy with everything done. I have loved the buying experience from this location as well as the people. My service agent, Harouna Fofana, was top notch! 10/10
2026 GMC Sierra 1500 SLT 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.
