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.

im not new to buying cars.

im not new to buying cars. ive owned hundreds and currently own 6 cars , 6 trucks and 3 motercycles. i however am new to the excellent service I received. Ill never buy a car from anywhere else. Bergeys team were the most knowledgeable and and easy to deal with ever. Then theres the deal part. no other place could even come close to what they came up with for me. if I had to describe everything in brief , " like a well oiled machine" When It came time to show me how everything works 3 of the Bergeys team came out. and all my questions was answered. I made the best choice ever Going to Bergeys GMC. The kind of place where you can stop anytime with questions and its not a bother

Steven Ahern! Best salesman you could ask for!

If you are in the market for another vehicle, please go Steve Ahern! He will take care of you. Amazing customer service. The best! He went out of his way to get me what I wanted. Even though I did decide to go a different route, I couldn’t have had any better customer service than what he offered.

I recently visited Granite Run GMC and with worked with Jimmy Tatlon and there are no words to describe how happy I was with the experience. Jimmy was friendly, knowledgeable, patiently answered all my questions. Although, I did not buy the pre-owned car I looked at but instead I am going to buy a new car in a couple months, and I am looking forward to working with Jimmy on the purchase. Overall, I was very pleased with how he assisted me. This is why I am giving Jimmy 5 stars!

Patriot Buick GMC review

I originally went just to see if they had anything I was

I originally went just to see if they had anything I was interested in buying when i was shopping for a used car. I ended up buying my truck from them and the transaction was very smooth and everything was explained in detail. I received free routine service with my purchase, so I went back for oil changes and inspections that were included but have continued after the free services have stopped because the people are so nice and make sure to explain everything and never do anything without asking or explaining bot what needs done and the cost upfront.
