yes we do run these days very close to break even to keep costs low for those taking part. At some events in the past we, literally have just covered our costs, and probably made a small loss by the time credit card charges are taken into account, but it tends to even out over the course of a year.
Most of our events do take a few weeks to sell out, but the Time Attack one last year sold out in under 7 days, so I knew this one would as well.
In terms of percentages - SE probably account for about 30 - 35% of the field, Imprezas/Evos about the same(slightly higher for this next event). SIDC/MLR members account for about 50% overall, which shows a few SE'ers are members also

I think the Dreadnought nights are something like £60 or £70 for a two hour evening session mid-week, and we charge £100/£110 for a 4 hour weekend session at peak times which includes free instruction and Wheel/Tyre van. I don't suppose our prices are too bad when you look at thing that way.
I'm certainly not expecting our next two events of the year to sell out so quickly.
Look forward to seeing you again, and you'll get some good photos if you stay around for the whole weekend with the Time Attack/drifting taking place in the afternoon and on the Sunday. I'm hoping to stay down for the whole weekend if I can get a weekend pass
