You think you friend is a stupid ass? From reading your posts and seeing how poorly written they are, I must say that you are the "stupid ass." Leave your friend alone. He seems smarter than you, he's not making fun of his friend just because he's new and he doesn't know much about his car. At least he's trying to learn, and I really don't think your doing your part to help him. Then again, I think any advice you give him shouldn't be taken seriously.
