If you look at the following pages (also accessible through the Goodwood website) it gives you the results for each class of car and provides a list of everything that went up the hill, either as a demo or for a time.

There were also a lot more classic cars from all classes that were static for viewing in the paddock area.
I hope that gives a flavour at least of what was there
