The Goodwood Festival of Speed is on at the moment (I have been there today). If you want a sense of it there is a live stream on YouTube:
Goodwood Road & Racing Channel.
I'd agree with previous comments that if you chose one it should be the Revival. Be aware tickets sell quickly (Saturday for this year sold out in April). Accommodation in the area also gets booked a long way ahead (I'm told).
