I got a collapsible from the parts dept, it was fitted on collection, the sub fits inside it. Not cheap at about £500 but they do seem to come up on the second hand market.

Don't think a full size one would fit in the back without taking up most of the boot!

the dealer is telling me the smallest size wheel that will fit on the SQ5 is 20 inch and they dont do a 20 inch wheel in a space saver ??????

He's talking mince mate, the collapsible is an 18"
