I asked him some questions regarding the vehicle I was interested in purchasing and the next morning without me asking he texted me and answered all my questions and even sent me pictures!! I told him I would not be able to see the vehicles until the weekend and Friday AM MARK PRESTON reached out, confirmed the vehicle was available, confirmed our 9:00AM appointment and when we arrived he was early, prepared for the test drive and within less than 2 hours, we were driving out with our new vehicle!!
