I leased an Acadia from AutoNation. The entire experience was very positive and unlike dealerships I have dealt with in the past.
My salesman was Miguel. He was knowledgeable and professional. I never felt pressured and instead thought the dealership worked with me to make a deal. Never did I feel the adversarial conflict that almost always happens when buying a car. Miguel took his time and introduced me to key staff members. He went over the features on the Acadia with me. He has followed up multiple times since the sale to offer assistance.
Finally a good car buying experience.
