I recommend Stevens 112 Ford. Look up Carmine.
Excellent experience buying a 2020 Ford Expedition Limited MAX SUV because my salesperson, Carmine Randello was honest and helpful rather than pushy. Carmine had a way of making me want the car without trying to make me want it.
Best truck I have ever owned.
Best truck I have ever owned. Used to tow a heavy RV. Wonderful comfortable ride. Highly recommended this truck. I drive it as my primary vehicle.

I have purchased three different vehicles from this
I have purchased three different vehicles from this dealer, and each experience has been great. I never felt pressured to purchase something I did not want. Good selection of vehicles. Robby was great. He is new to this work, he did follow up to make sure eveything is going great with the purchase. I would like to see this dealership work on the service department more, as I had multiple issues getting my vehicles serviced at this location.
well put together vehicle
The truck met all my expectations and more so far. the engine is powerful and the ride is smooth. the interior is great and so are the things this truck has.

Capital Buick GMC
The deanship has excellent service. Dan Cash is the man to see he is excellent with customer service and treats you with respect and honesty.
Versatile and comfortable hauler
This SRW truck carries a slide-in truck camper and tows a boat when it's not a daily driver. The gas 6.0L is very capable to handle both and the truck is comfortable riding when not loaded down. Reliable engine and truck.

I ordered my 2024 GMC Sierra 2500 diesel from Junction
I ordered my 2024 GMC Sierra 2500 diesel from Junction Auto almost a year ago. Corey Turnbull was my salesman and he did a wonderful job helping me through the ordering process. He is very knowledgeable and made the whole experience enjoyable. This is now the 2nd truck I have ordered from Junction, and both times it has been a good experience! Douglas Haw D.W.

Great truck
This is a very clean, serviced and useable truck. I "live" in my truck and needed reliability, but without the garish price of new. All my tools fit and it is very handsome interior and exterior.

Eight days ago, I visited this dealership, and it was
Eight days ago, I visited this dealership, and it was truly one of the best experiences I’ve ever had. From the moment we walked in, the service was outstanding. We were greeted by Hubert, who was exceptional, confident, and professional from the very start. Thanks to him, we felt secure and ready to take the step of purchasing the car we had been searching for. We then continued the process with Francisco, a true professional who made us feel completely at home. We also want to thank Jeffrey and Lidia, who made everything so much easier and smoother. I highly recommend this place and their amazing team if you’re looking for your ideal car. I absolutely love mine, and I’m beyond satisfied with both the vehicle and the incredible experience I had that day. Thank you all so much!
