I highly recommend you to anyone interested in purchasing a vehicle from this Thank you so much Luis Morales for your outstanding customer service. I highly recommend you to anyone interested in purchasing a vehicle from this dealership. We can't thank you enough for being on time, having the vehicle ready for test drive, answered all our questions, kept us abreast of any financial questions that might arise and just friendly as can be. We didn't feel rushed or pushed, it was a perfect day. The fact that we drove 1.5 hours to get to you and how attentive you were with us, was icing on the cake. You are a gentleman and so easy to work with that the experience there was great. A person not listed below is our Finance person, Larry. What a wonderful man he is too. Thank you all. Who knows, we might be back for a Cadi! More
