I was in Chicago last week for the International Manufacturing Trade Show: incredibly cool with some massive booths showcasing amazing technology!
One of the larger booths - like 200x100 feet! - was Haas Machine Tools - better known to us as the Haas Formula One team. They had a car on display! Even at a year or two old, it is still the closest I've been to a modern F1 car.
The level of workmanship and detail boggles the mind. Check out the pictures to see what I mean, especially some of the aerodynamic and airflow management close up images.
