I beg to differ.
I think the only reason the rookie car is slower is because of the drivers, and not because of the car design cap.
0-50 in rookie is just made easier to build up the car earning such low design points. it's doing the same thing as the 0-75 pro or 0-100 elite cars.
I'm not reading the book, I'm just flicking through the pictures
Old system CD's had Cap levels. They should bring them back hehehe
