Way to sum it up Paul. While I have not driven a One, I would agree on the other two.
I test drove the Copper and the S when we were looking. I knew it was going to belong to the Mrs., so I knew it had to be the S. I just wanted to see if there was a difference. The seat of the pants feel is much quicker in the S, not that we get much chance to use it like it was intended.

But we make the most of it
