You could come in with me on a half-share - I'm looking for roughly the same thing. I had a Jodel, Luscombe or similar in mind.
Don't worry about folding the wing. It's a pain in the proverbial and anyway, whey not keep flying through the winter? You'll still be paying for the hangar even if the 'plane is at home.
I do have contacts with respect to hangerage etc......
I'm based in central south Hampshire - could be too far for you depending on where in Sussex you are based.
PM me if interested.
