Things to do around silverstone.

[Draven]

Not sure if this is the right place to ask this question but here goes ....

I'm going to be in silverstone doing a driving course in march and I'll be staying a few days.
I've been to the track before, but It's always been straight to the track and straight home again, since I'll have time I'd like to see any other sights of interest (motorsporty or otherwise, but cars first!) while I'm there.

I know the Jordan F1 base is there, (I'm Irish so I'd better go see it while I still can) and I'll have a rental car so I'm going to have a look at who else is within driving distance. Anybody know of anything i should go see?

Also since I only have to been near silverstone during the week I'm going to try and catch some racing somewhere the weekend before.
It's the weekend of the 13th of March and unfortunatly I'm having a tough time finding out what is on in Silverstone,Donnington and Rockingham that weekend. Their Web-sites dont say , so I guess nothing.
Anybody know of any other events on then?

Thanks in advance for any help.
