I want 2 write a letter to a company 2 attain its dealership in my city. A convincing letter.

Tell me please, why you think you would get a positive reply from the above note.

If you are seeking to create a business relationship with a parent corporation, you had better learn to structure a business letter. And the content of that letter had better be well written in grammatically correct English.

Consider introducing yourself to a Webster's Dictionary and studying the form the letter should take.

Good luck
