I'm looking at vehicles for my daughter. I asked what I thought was a very simple question. Are your Infinity's certified. I gave my name but no additional information as I did not feel at this point I needed to give any additional information for a simple question. You would have thought I asked them to move the world because the lady would not answer my question and instead never responded at all because I would not give any additional information.
