Awesome dealership
Brian is the best ..I wouldn't go any other place in Lancaster ..Thank you so much .. Wonderful service and great vehicles ! Thx Roger and Renee
This truck is the base model and that is exactly what we
This truck is the base model and that is exactly what we were looking for. A good solid truck without all the fancy technology. It drives like a dream, handles just as well and the interior is sleek and well designed. Perfect black on black exterior.... a man's truck.

The staff was very kind and helpful.
The staff was very kind and helpful. The Payment lady really knew her stuff. She helped to explain everything out and did not make me feel lesser than.
Failed transmission and full replacement
We have owned our GMC Sierra 1500 for approximately 9 years now. The only real disappointment with the vehicle is that we had to have a full transmission replacement Just after the 100k mile without any warning whatsoever. The truck now has 107k miles on it and now , again out of nowhere, we are experiencing slipping in the trans and the engine light is now flashing. Very disappointing since we are starting to feel uncertain about the reliability of the vehicle now. The truck itself is gorgeous and shows ZERO signs of its age, sporting new rims and tires and a lifted body and no rust on the body at all. We hope there are no major issues with the engine as the vehicle has always been maintained as needed and on time for regular servicing at the dealership.
