I am a husband and father of six with one Grandson. My wife and I have been married for 25 years now, and we look forward to another 25 years! I love to play golf, read Anne Rice novels, and to engage in good conversations. I believe that customer satisfaction is the core foundation of any business. If the customer is taken care of above and beyond what is expected, then everything else will fall into place.

I can’t say enough about Jason, my salesman. I went in, told him what I was looking for, and he listened! He gave me options. He was patient, and was very knowledgeable. He wasn’t pushy l I went in, told him what I was looking for, and he listened! He gave me options. He was patient, and was very knowledgeable. He wasn’t pushy like the others, he let ME decide. How could I say “No deal” after his 7 hours of patience. All the staff was so friendly and welcoming, and I would definitely come back. THANK YOU JASON!!!! More

Jason was a patient salesman since it took me a while to make a decision. He helped me look at all the pros and cons of different models. AJ, Adam, Gus & Caden were also helpful with the sale.
