Why would we need to run a space saver? I acknowledge that there is a risk of running a flat, but most of us would judge that risk as being minimal. Even if there was a space saver tyre, I would remove it anyway to save some weight, as I've done with all my previous cars. If you want a car with a space saver, then maybe the 1M wasn't the right choice of car. Just saying.
