As a follow up to this post, you might be glad (as I was) to find out that the Mini is in fact not as badly damaged as I thought. It has a fair bit of bent metal and broken plastic, but nothing structural was damaged.

At the time, the car span round about 90 degrees, and it felt like being hit by a truck, so this is good news. Flip will ride again! (soon)

Thanks for all the pleasant wishes, everyone.
