I've only just discovered that this is today, so sorry for short notice..
Details here (http://www.petermadden.co.uk/) but it's basically a classic car show in a (surprise surprise) walled off garden inside the grounds of Luton Hoo Estate!
It's apparently cars from the turn of the 19th Century, and is run by the guy who started Classics on the Common (those of you close to Hertfordshire will hopefully have heard of that 
).
I'm planning to head down after work later, if anyone in the Herts / Beds area is planning on going too then let me know!
