Formal Letter

Dear Sir Cooper Brown,
I am writing this letter because I want to sell you my machine. It is new. I bougth it yesterday. I am selling  it for US$500. It is a very good price, very cheap.
  -The component's of the machine are: Engine 2.0V7, wheels(for transporting) , and a pocket to save things. The appareance is very beautiful.. The colour is black and yellow. This machine is for travelling to the future. The button to travel to the does not work. That is the reason why it is very cheap. The most exciting thing of this is that you can see the bad things that you are going  to do and change them.

Yours sincerely
                       Steve Carlson        ST
