This is one of my favorite styles of writing. I have absolutely no clue what this person is talking about and have no interest in cars, yet I read every single word. I love when people have such a deep knowledge of something that they can write an essay as unique and thoughtful as this. It reminds me of Kitchen Confidential, Surely You're Joking Mr Feynman!, or any rant about British politics by David Mitchell.
The fact this essay works for someone with limited domain knowledge and someone with lots is a testament to the quality of writing.
