Geoff Penske GMC review

Very responsive.

Very responsive. They were straight shooters and were able to find ways to meet our goals.

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.

Hill Buick GMC review

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.

MIRACLE BUICK GMC OF KUTZTOWN review

The first day I showed up no one assisted me or asked me

The first day I showed up no one assisted me or asked me any questions so I left. I then reached out asking if the vehicle was still available and was responded to very quickly. When I showed up to look Jeremy helped me right away and was very kind. Let me see all the seats because I am looking for a third row. Unfortunately that car was not right for me and he didn’t make me feel bad or like I wasted his time he was just happy to help me. I really appreciated that.

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
