Update: I was contacted by Kyle and he arrange for me to meet the owner today (monday). We meet up with Shawn and explain the entire situation my father medical history and all. He was very under and even help us out so that this can neve happen again with our dad. After talking we realize that the employee yesterday really had no jurisdiction on helping our situation and that is why it seemed we were getting the run around. The meeting concluded with both parties being satisfied and not taking so much of a lost. I would once again thank employee Kyle for reaching out and to the owner Shawn Saggart for being understanding and working with us. Based on our experience today which was very informative if I had to buy a car this will be the place I go. So my father who had a stroke and is mentally delayed purchased a car from here. That is not the problem. The problem is the next day we went to explain the situation and try to talk to the company and r w solve this matter on taking back the car. However, we were given the run around. We went to tent sale where the car was purchased. Upon entering explain the situation was told go see the boss in the back. Went to the back the boss ask why we would like to return, explained again he then told us have to see the boss at the main office. Went to the main office and explain to the boss there again the situation. He then tells us that he can not help us we have to talk to the owner who will not be back until Tuesday (2 days). When we ask the time he states to call and make sure the owner is in on Tuesday somewhere around 10am. Right now this seems very uprofessional. We are trying to resolve it without taking legal action. However if business runs like this on Tuesday like today, we may have to take legal action. We have already contact our lawyer. Will update as the situation goes along.

I was very pleased with the service I received at Rock Auto Group on 2/17/18.My salesperson Bob was extremely helpful and patient. He followed us home so I could retrieve ,sign and He then returned it to Rock Auto..saving us a trip. He also rode with us to the Credit Union , and answered several questions that was needed in order to process my loan papers. He is pleasant and soft spoken.
