Excellent experience. We arrived and Cory was waiting for us in the parking lot. He had the Alpha already set up for us to look at but was also willing to show us anything else we wanted to see. He was laid back and friendly and not pushy in any way. Everyone was super friendly. The store was cute and cozy and had a real nice family feel. It felt like the kind of place you'd like to work yourself - Christina
