What Track Day Car for £27k?

[Markymark01]

Hi all
I'm looking for a trackday car thats also road legal for blasts on a Sunday.
I have some very fast sports bikes, so want something that will be a bit swift, but that the other half will get in!
Currently thinking an Aerial Atom but i notice there are lots of options of less well known cars that are similar.
I'd appreciate your thoughts
Thanks
Mark

Thanks for all the suggestions....seem the Caterham is the favoured route.
I've got an atom hired for a track day tomorrow.
Thank you for all your input....
