Pushy salesman

I get contacted almost every day by a company that is selling insurance on behalf of Miway. Yesterday, I accidentally answered one of these calls. In a moment of weakness, I decided to hear the guy out. I actually almost changed insurance companies, but when I told the guy I wanted to read through the documents he was going to email me before I made the commitment, he did his very best to dissuade me from having a look at the documents first. He even gave me a cheaper price if I signed up then and there and even gave me some stupid analogy. He said, 'If my car was broken, I would take it to a mechanic and trust his advice.' In this analogy, the sales guy was the mechanic, and I should just trust the guy who is trying to make his commission.
