Billion Auto - Buick GMC review
Excellent.
Excellent. Matt the salesman was patient and very knowledgeable. We had a list of wants, which he found and more. All the Billions employees were friendly, even if just a smile and nod. We love our 2024 GMC with lots of cameras. I have bought at Billion several times. I have always recommended Billion to Friends and they purchased cars from Matt.

Very Efficent and positive experience purchasing my vehicle. I was very specific with the features I wanted and they were able to find the vehicle with those specific features .
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.

Billion Auto - Buick GMC review
I had an outstanding experience getting my 2022 Chevy
I had an outstanding experience getting my 2022 Chevy Traverse serviced here. After bringing it in for a transmission issue, the team diagnosed it quickly and even provided a ride home so I could finish my workday. My service advisor, Brian, was exceptional?he stayed in constant contact with updates. I was relieved to find out the replacement was covered under the powertrain warranty. They sourced a new transmission locally and finished the job right on schedule. They even picked me up to collect my vehicle! I?m driving away with total peace of mind. Highly recommend Brian and this service department.
