Is anyone interested in this before I put it on that well known auction site?

£50. Collection only.

Whereabouts in the fair isle are you Woolly?

High Wycombe, Buckinghamshire.

Is this compatible with a spare wheel? I think I tried to spec one on my Cross and was told it's not, but from your pic I can't see why.

As long as it's a space-saving tyre, it should be OK. I can only speak about a 2WD model.

Thanks. I guess this isn't the same product as I thought, which is the 'cargo box' and is much deeper.

I think Cargo Box is the correct name for this. I'm pretty sure that there's only one type offered by Fiat.
