I bought this particular wheel as it is the factory standard for my car and matches the other four. I have never been happy to travel without a spare and at the asking price it was less than half the cost of a new wheel direct from BMW. I replaced the supplied tyre to match my own and it was still cheaper than a new spare.
If you are intending to obtain a spare for your own car I strongly suggest you match it by Model AND manufacturers part number, there's a confusing array of options for BMW wheels !!
