I've been doing a bit of organising under the boot floor, as I also opted for the non-runflat tyres so I've got a space-saver and jack in case of a flat...
The jack and wrench handle are packed in a unnecessarily large polystyrene block, so I've replaced this with a couple of boot bags from Amazon. There's room in there for the jack, handle, jump leads, compressor, a few tools, spare oil bottle and quite a bit more.
I also bought a wheel bag in case the worst should happen and I have to carry a full size (flat) wheel in the boot, as this certainly wouldn't fit under the floor. It remains to be seen (but hopefully not!) how the dog would feel about sharing his space with a big red bag
