April was a pleasure to deal with over the phone.  Cheryl was excellent in the service department and Michael didn't leave stone unturned in the service department and customer orientation.  We even had extra items added without any complaints!

Excellent!  Everyone was so helpful and friendly.  We will be recommending this dealership to everyone we know.  IT WAS WORTH THE 13 HOUR DRIVE FROM NORTH CAROLINA!
