What's best for the customer
Chris Green was great. He was attentive to our needs and personable, showed options, was responsive to our inquiries, was insightful on the models, but was understanding that our best fit for our needs may not be a Ford (was at Shottenkirk Toyota, also highly recommend). We appreciate his candor, will always ensure to recommend him to all we know, and look forward to coming back to him when time to get a F250.
Great Buy!
This truck is amazing. Turning heads all over as we tour the area. Those riding with is also enjoy the comforts and safety features. Great Buy!

My experience at this dealership was great!
My experience at this dealership was great! Garret was my salesperson and he was very experienced and did a great job helping with my car purchase. He gave me the keys and I knew it was the one. I test drove the car and it drove perfectly. The tires looked pretty new and the inside had no damage. The cars on their lot are very clean and maintained. Sam was who I worked with on the financing and he was very thorough in explaining all the options that I had. All the people there that I met were very nice and friendly. I would definitely recommend this car dealership.
