The sale person promised with me that she will discount $500 on my car and I agreed to sign up for many document. However, when I went home, I figured out that she didn't put that discount amount into my contract. I came back to ask but the financial explained the big number in my contact likes he never attended a math class before. I had a big argument with them, and later they brought me to another person. At here, this girl explained a little bit clear and made sense about the big number in my contract. Finally, we figured out that there were two things wrong: first, the sale person didn't put the $500 discount into my contract( she cheated me). Second, the financial manager didn't know any thing about the optional service amount on my car $1,208,and he just wrote it down. That's explained why my car price increases higher than when I made a deal. I recommended people who bought a car at here should check the unclear numbers which appear on your contract again.
