Where to hire Ariel Atom or Caterham R300?

[alfa daley]

PHer's, hoping you can help I'm looking for somewhere that hires out for road use Ariel Atom's or Caterham's that aren't the roadsport/sigma engined versions, so Superlight R300/400/500 or CSR260. There don't seem to be any companies in the South/nr London offering this.

I did try a Caterham SV a few years back and whilst fun, it would have been even better with a bit more poke.

Any recommendations?
