Living approximately 100 miles from Knoxville, we began our negotiations for a used vehicle for our son by phone with Frank Cardwell and then completed the transaction with him at the dealership. Although I am a "somewhat difficult" person to deal with when it comes to buying a vehicle (something I always dread doing), Frank never became impatient. He cheerfully and knowledgeably answered every question we asked him. He could not have been nicer or more helpful. Also, Terri and Debbie were superb in quickly and efficiently finalizing the paperwork. (Thanks, Terri, for the sweet compliment.) As we left the dealership with our spotlessly detailed, completely filled vehicle, we realized that our whole "dreaded" purchasing experience had ended up being totally enjoyable! Many thanks to Frank and everyone else at Mercedes-Benz of Knoxville for a wonderful experience and a great vehicle!
