I have recently bought a Clubman Cooper D. I took it to France and managed to get a puncture. There was no repair kit and the wheel was seized on (forgot to pack the WD40). I want to carry a spacesaver on future trips to France and want to know: 1. Will it fit inside the well inside the car under the panel above the jack and wheel brace? I would prefer to do this than fit the underfloor kit, but that may be the solution. 2. Most of the spacesavers I've seen on Ebay are 15ins. Has anyone experienced driving with one 15in spacesaver and 3 standard 16in wheels. I've spoken to a tyre expert who thinks it is okay but talked about 'rolling diameters' which I would have thought were irrelevant for an emergency limited journey on a spacesaver. For anyone travelling in France, my breakdown guy didn't speak a word of English and my French is very limited. A French phrase book saved the day. Any advice welcomed (about the wheel not my French!)
