Where were all the classics going eastbound on A272 Sunday?

I was heading west from Five Ashes to Cowfold and passed loads of classics, Mercs, MGs, Healey, etc heading eastbound.
Was it an organised run, or were you all heading to an event?
A nice collection of cars

I noticed them too (inbetween all the bikers).
