As ALWAYS VERY CURTIOUS AND PROFESSIONAL FROM THE MOMENT
As ALWAYS VERY CURTIOUS AND PROFESSIONAL FROM THE MOMENT i WALK THROUGH THE DOOR. The facility is well maintained and the staff is very interested in serving my needs as a customer.
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.

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 had 2 issues following my Detail visit. One involved unfinished cleaning of my dashboard area which was promptly remedied. The other was a missing letter ?K? from the rear of my car. New letters were ordered and I will make an appt this week to have them applied. Everyone was agreeable and most courteous.

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
