Lute Riley Honda

I was looking for a 2012 Honda Civic LX, and compared the quotes from different dealers via Edmunds.com. Lute Riley was not the lowest one, but the internet sales manager promise to beat any others by $500, and it is close to my home, so I went to the dealership and met a sales person whose name is Ken. I was very disappointed meeting with this gentleman. He is not honest and inpatient. He first told me there are two Honda civic 2012 LX in stock, but later on he said all sold out, and push EX and 2013 LX to us. When we leaving the dealership, he called me and said he has LX again and asked me to come back. The price offered by this gentleman is far far more than the internet quote, even more than other dealers 2013 LX. He said Lute Riley does not any discount, not even a penny, I showed him the internet quote, he said it was the trick to attract people coming in. Couple mins later he change his word said your price does not include the equipment installed. I dont see any point I should go ahead doing business with this dishonest people or company, even they had got the lowest price.
