Aside from the obvious electric / gasoline differences, what do you think each car really says, between the Model 3, Audi A4, BMW 3 Series, and Mercedes C class? Here is my interpretation. 1. Model 3 - I can afford to drive a Tesla, and you can't! Between your car and mine, I win. 2. Audi A4 - It's nice, but not amazingly outstanding. German engineering, I guess. 3. BMW 3 series - Now there are 7 million AND ONE of them on the streets of America! 4. Mercedes C class - I couldn't afford a real Mercedes, so I got the Cheap, Crappy, Compact version. I'm a wannabe. That's how I see them, anyway.
