I will never buy a GMC from anywhere else.
I will never buy a GMC from anywhere else. The dealership and people are real and not fake flashy like others. I drive further to get my vehicle serviced there over Jerry Seiner because of the quality, timeliness and communication from the staff.
This truck has a jerk when changing gears sometimes.

Radio Replacement
Took the car in for backup camera problems and frozen pictures on the screen. Dealership troubleshot problem to radio/screen display. Ordered a new radio, and less than a week later, called me to schedule an appointment to replace it. Flawless execution from this Service department, which is their standard!

We bought a 2023 Ford Explorer ST last month at Autolocity. We had a great experience. They had excellent Customer Service and were very friendly. The car was a great price. They were also able to help us find the car that met our needs and answer any questions we had. They were very quick with the paper work and got us on our way. This is the 2nd car we've purchased from Autolocity. We will definitely purchase from them again.

EXCELLENT experience again!!
We just purchased our 2nd vehicle from Kentson Car Company and we will definitely be back again! The selection is great and the shopping process is amazing!! We worked with Mark both times and he is a pleasure to work with. There is absolutely no pressure, he's very informative and helpful, and you test drive without having a salesman breathing down your neck on the ride. There is definitely a completely different feel than shopping for and purchasing a vehicle anywhere else. Once we made our decision the paperwork took literally 15 minutes. They even arranged for us to get the front windows tinted promptly before heading home. EXCELLENT experience from start to finish!!!

I had a recall with my GMC truck and Cody was great
I had a recall with my GMC truck and Cody was great helping me set up a time to have it fixed. They were fast fixing the issue and called me when it was done. When I returned to pick up my truck I asked about an antenna issue I was having and they had an antenna in stock and replaced it in just a few minutes. Great service I wouldn’t hesitate to do business with Hansen’s Service Center again. Thank you! Tom
