Franklin and Gwen, Thank you so much for taking the time to leave us a review! We do apologize for the lack of initial contact upon your first visit, we unfortunately had only one salesman on the lot that day. We are thankful that you were able to stop back and Kyle is so pleased that he was a part of helping you take home your new white 2026 Maverick! 😊 Thank you again for your review and we look forward to seeing you again in the future!
