Message sent directly to salesperson: Hanna, I will be
Message sent directly to salesperson: Hanna, I will be recommending YOU whenever I know of someone looking for a vehicle. When someone is making a major purchase, like buying a car, it is so important to have a sales person with genuine integrity and relentless focus on the customer. Your communication throughout the process has been stellar; always keeping me updated. I appreciated that you not only focused on the sale, but also on doing proactive work to facilitate a smooth transaction on a specific day, with my family's needs in mind. That 'extra' means a lot!
