Thanks. I have submitted a complain to BBB on May-29,

5 days later buying the new car on May-24.
However, I hope to know if there is a better and fast way to
solve my problem.
In fact, I ask a lowest package, but he gave me a higher one.
I ask light blue color, or light green, but he told me there is no
the two kind of color for this package. However, my freind
found there are two days later after I bough the car.

You see a lot of trick there, big and small.
Too sad.
