Anne was an excellent salesperson. She took her time to show us and help us over several months. Always gracious and considerate until we made a decision. We got a fair trade and a great deal.
Much in contrast to an unnamed out of town place where we were under intense pressure to buy the moment we stepped inside.
The rest of the staff were equally helpful. Financing was easy and straightforward. - Joe
