At UK car meets in places like Goodwood you can see the early Newey cars in the pits up close. They are good to see as much of F1 design is different to normal automotive, parts only have to last the race to some extent. Fasteners can be quite primitive, it isn't all high tech.
In the flesh the cars are smaller than you think so, with only fun day carting to compare with, you wonder how such aero changes could make a difference. This makes it more fascinating.
