The Ulster Kit Car Club is based here in Northern Ireland and looks after all those wishing to DIY their vehicle, including quite a few se7ens.   There's a good gallery of photos which appears to have nearly every type of se7en, with the notable omission of a Caterham Seven.  Hmm.

I'm a bit ashamed to say that these guys meet about ten miles away from where I live, but I've never called in.  Perhaps addressing that'll be an early New Year's resolution.
