How do you write a motivation letter for car allowance?

A motivation, or cover letter of any kind needs to be brief. Its only purpose is to draw attention to the actual application that it is sent with. This applies when the letter is covering an application for an allowance to cover car expenses. As most of the information will be in the application, only a single sentence would be appropriate outlining the reasons that the application should be considered. Its form should be in the manner of any other short business letter.
