There's always the Classic Le Mans. Has been on my do list for ages.
http://www.lemansclassic.com/en/s01_home/s01p01_home.phpProper cars with distributors, carbs and ruddy great straight sixes where you pour the petrol in from a jerry can while smoking a pipe. None of that diseasel nonsense either.

It has to be said, the unique thing about Le Mans is watching it at night. There is no experience like watching the headlights of an LMP accelerate out of Tertre Rouge towards you, up through 5 gears, over the crest (at this point, if it's a Merc, they take off

) and up another gear before a quick glow on the brake disks, round the chicane and back on the gas. 8-) You
really appreciate how fast they are at night.

If you've got camping sorted you can just turn up, TBH. Might be worth booking parking but have turned up on impulse before and been fine.
Camping? I like this place.

with the hottest barmaids... <cough!> Anyway, yes, we should go. Meet you at Portsmouth in 45 minutes?
