I saw an Ad on Acura MDX under the used car section and decided to have a test drive. After the test drive I made a mistake of giving my visitor card. I believe they thought I was a well to do person and I will pay what ever price they have quoted for the used car. I called the next day and told them that I will put an offer. The moment the sales guy heard that he was disgruntled even before I had an opportunity to put my offer. He was like, This car is on sale. What do you mean putting an offer blah blah blah. When I put forth my offer after listening to his nonsense, He was agitated. Their sales guy does not even have the decency to politely refuse. Instead he says that he is not in the business of selling cars at a loss. Well even I am not in the business of paying sticker price for a car. Perhaps that's how they treat a used car buyer.
