S5 cab vs folding bike

[Output Flange]

Random one, I grant:

Does anyone know of a folding bike that will fit in the boot of a '14 plate S5 cab with the roof down?

Obviously I can trawl the specs of every model to check, but if anyone has experience and shortcut that for me, it'd be appreciated!

I dont have a folding bike but i do have an S5 cabriolet, with the roof box down (roof open) there is 25cm height wise, with the roof up and roof box folded away theres 36cm. My mountain bike will go in with the rear seats folded but the roof has to be up.
