In Class: what about the essay worries me?

im worried that the readers will not be able to relate at all to my feelings about my car. the topic might not be something most people will understand fully. i also dont know how i am gonna write 5-7 pages of stuff about my topic. sure i love my Muscle car and i love drag racing but there is only so much i can really say about it. i never get writers block and i always find something to say but at the same time for this particullar essay i dont know if it will be like that. i might not have to much time to work on it if i want to enjoy my weekend at all..
