I purchased a used Hyundai Santa Fe from Mark Preston. Mark was a professional all the way. Between my dad being in the car business when I was growing up and being married for over 30 years, this was the Mark was a professional all the way. Between my dad being in the car business when I was growing up and being married for over 30 years, this was the first time I bought a car on my own. Mark answered all my questions, and since he was the person who had made the deal for the car I purchased as a trade-in, he was able to assure me that the car was in excellent shape. I have had the car for about a month now and have taken 2 trips to AL to see my parents. It has operated flawlessly, and I have to admit, driving a cute, shiny red car is fun! Thank you for your help, Mark, and thank you for your service to our country. Goran was also very professional. He got me through all the paperwork quickly and efficiently. Both Goran and Mark gave me their full attention and treated the transaction as important, even though it was for a lower-priced used car. I appreciate the wonderful customer service! More

We had no intention of purchasing a car at Infiniti of Gwinnett, however, we were looking to see what might interest us in our next vehicle. Upon arrival, a sales person approached us, introducing himself Gwinnett, however, we were looking to see what might interest us in our next vehicle. Upon arrival, a sales person approached us, introducing himself, Mark Preston. He was very informative and knew everything about the Infiniti brand. He expressed “No Haggle” on all vehicles, which we could appreciate! We secured the vehicle we wanted on Saturday and sealed the deal Monday! Mark was very straight forward and dressed to impressed we might add! if you are searching for a vehicle that has luxury and all the amenities, call Mark! Thank you, The Lunsford’s More
